2017 Chicago Cubs season

The 2017 Chicago Cubs season was the 146th season of the Chicago Cubs franchise, the 142nd in the National League and the Cubs' 102nd season at Wrigley Field. The Cubs were managed by Joe Maddon, in his third year as Cubs manager, and played their home games at Wrigley Field as members of the National League Central Division.

The Cubs were the defending World Series champions, having defeated the Cleveland Indians in the 2016 World Series.

The Cubs began the season on April 2, 2017, at the St. Louis Cardinals and finished the regular season October 1 at home against the Cincinnati Reds. The Cubs finished the season 92–70 in first place in the Central Division. With a win over the Cardinals on September 27, the Cubs won the division title for the second consecutive year.

The Cubs defeated the Washington Nationals in the National League Division Series three games to two to advance to face the Los Angeles Dodgers in the League Championship Series in a rematch of the previous year's series. In the best of seven NLCS, the Cubs lost to the Dodgers four games to one.

Previous season

The Cubs finished the 2016 season 103–58 in first place in the Central Division, reaching the playoffs for the second consecutive season. The Cubs defeated the San Francisco Giants three games to one in the National League Division Series. In the National League Championship Series, the Cubs defeated the Los Angeles Dodgers four games to two to advance the franchise's first World Series since 1945. In the World Series, the Cubs rallied from a three games to one deficit to defeat the Cleveland Indians to win the World Series for the first time since 1908.

Offseason

Wrigley Field renovations

The Cubs continued their $500 million, multiyear renovation project at Wrigley Field. Changes to the stadium for the 2017 season included:
* Relocated bullpens – Both bullpens, previously located down the first and third base lines, have been moved to their new locations under the bleachers in left (home bullpen) and right (visitor bullpen). The bullpens have windows that allow fans in the bleachers to look into each bullpen. Green-tinted transparent doors lead on to the field which allow the players see the game action, but cannot be seen through from the field.
* New rows of seats – Where the bullpens were located, down each line, four rows of seats were added.
* Seats behind home plate replaced – All seating in the lower bull behind home plate were replaced. An area underneath the seats will eventually become the American Airlines 1914 Club. Of the new seats, 700 were padded will be part of the Club in 2018.
* Partial facade restoration – The facade facing Addison Street was restored to match earlier changes to the west facade.
* Concourse replaced – The right field concourse was replaced with new bathrooms and additional concession stands.
* Office building and The Park at Wrigley – To the west of Wrigley Field, the Cubs built a new office building for organization offices. A plaza named The Park at Wrigley with stores and video monitors was added and can be used by the neighborhood when the Cubs are not playing at home.

April

* April 2 – On opening night in St. Louis, Willson Contreras homered in the ninth to tie the game before the Cubs lost in the bottom half of the ninth. The loss marked the first time since the third game of 2015 that the Cubs record was under .500.
* April 4 – Jake Arrieta pitched six strong innings while allowing one run against the Cardinals. Jason Heyward and Javier Báez each drove in a run in the fifth as the Cubs won 2–1.
* April 6 – After a rainout the prior day, John Lackey gave up four runs in six innings, but the Cub bullpen held the Cardinals in check thereafter. Kyle Schwarber hit a three-run home run in the seventh to give the Cubs the lead and Wade Davis got the save as the Cubs won 6–4.
* April 7 – Kris Bryant flew out to right field in the first inning to move to 0–14 on the season. The start marked the worst start to a season by a reigning MVP. However, the Cubs went into extra innings tied at one against the Milwaukee Brewers at Miller Park. In extra innings, Mike Montgomery threw a wild pitch with the bases loaded to allow the winning run to score as the Cubs fell 2–1.
* April 8 – The Cub offense awoke in game two against the Brewers as Kris Bryant had three hits and drove in three runs while Willson Contreras, Javier Báez, and Albert Almora Jr. each drove in two. Kyle Hendricks, who chipped in offensively with two hits himself, allowed four runs in six innings of work as the Cubs won easily 11–6.
* April 9 – In the final game of the series, Addison Russell doubled with the bases loaded and Jason Heyward tripled in the first inning to give the Cubs an early lead on the Brewers. Jake Arrieta pitched seven innings while allowing three runs while Heyward drove in three runs as the Cubs beat the Brewers 7–4.
* April 10 – On opening night at Wrigley Field against the Los Angeles Dodgers, the Cubs raised their World Series banner following a rain delay of over an hour. Kyle Schwarber walked three times as the Cubs won the game with a walk-off single by Anthony Rizzo in the bottom of the ninth inning 2–1.
* April 12 – John Lackey gave up a run in the first, but pitched six strong innings as the Cubs struggled against the Dodger pitching, losing 2–0.
* April 13 – Brett Anderson pitched five innings and allowed no runs as the Cub bullpen also shut out the Dodgers. Anthony Rizzo homered and drove in two runs as Addison Russell also homered leading the Cubs to a 4–0 shutout victory.
* April 14 – Kyle Hendricks gave up three runs in five innings as the Pittsburgh Pirates came to Chicago. Ben Zobrist and Kyle Schwarber drove in a run each for the Cubs, but it was not enough as the Cubs fell 4–2.
* April 15 – The Cubs took an early 6–2 lead on the Pirates behind two Kris Bryant home runs and three RBIs, but the Cub bullpen gave up five runs in the seventh as the Cubs lost 8–7.
* April 16 – The Cubs were swept by the Pirates at Wrigley Field losing 6–1. RHP Koji Uehara gave up three runs in the top of the eighth inning to end his scoreless inning streak at 20 innings. The Cubs fell to .500 on the season.
* April 17 – With the Brewers in town, the Cubs lost their fourth straight game, losing 6–3. John Lackey allowed four runs in six innings as the Cub offense struggled. The loss dropped the Cubs record to 6–7, marking the first time they had a losing record that late into a season since their last-place finish in 2014.
* April 18 – Looking to avoid a fifth straight loss, Brett Anderson gave up six runs in 3.2 innings of work and left the game trailing 5–2. However, Miguel Montero homered to tighten the score and the Cubs pushed across four runs in the sixth inning to beat the Brewers 9–7.
* April 19 – Kyle Hendricks gave up four runs in five innings and left with the Cubs trailing 4–1. The Cubs battled back and trailed by one entering the ninth inning Kris Bryant drove in the tying run and Addison Russell hit a game-winning, two-out, three-run home run the Cubs came from behind to beat the Brewers 7–4.
* April 20 – Jon Lester gave up five runs in 5.2 innings as the Cubs traveled to Cincinnati. Trailing the Reds 5–2 in the top of the ninth, Anthony Rizzo hit a three-run game-tying home run to send the game to extra innings. In the 11th, Kris Bryant drove in the winning run on a sacrifice fly as the Cubs extended their winning streak to three games and moved into sole possession of first place.
* April 21 – The Cubs belted three homers against the Reds including a grand slam by Willson Contreras, his first career grand slam. Anthony Rizzo and Jason Heyward homered for the second straight game as the Cubs extended their winning streak to four games by beating the Reds 12–8. The Cubs have homered in each of their last 14 games in Cincinnati.
* April 22 – John Lackey gave up seven runs in six innings of work as the Cubs fell to the Red 7–5. Anthony Rizzo homered for the third straight game and drove in two runs, but it was not enough to overcome Lackey's poor start.
* April 24 – The Cubs traveled to Pittsburgh and jumped early on the Pirates scoring nine runs in the first three innings. Jason Heyward homered for the third straight game and drove in four runs and Ben Zobrist drove in three as the Cubs hammered the Pirates 14–3.
* April 25 – Kyle Hendricks pitched six strong innings and the Cub bullpen shut out the Pirates. The only run of the game scored on an error by Pirate second baseman Alen Hanson in the second inning as the Cubs won 1–0.
* April 26 – Looking for the sweep, Jon Lester gave up six runs on 10 hits in 5.2 innings. Anthony Rizzo homered and drove in four runs, but it was not enough as the Cubs fell 6–5.
* April 28 – In their first interleague game of the year against the Boston Red Sox at Fenway Park, Kris Bryant homered in his first at-bat at Fenway, the stadium where his father, a Red Sox minor-leaguer, proposed to his mom. Jake Arrieta struggled early as the Cubs fell behind 5–1 and lasted only 4.1/innings. Despite a homer by Albert Almora Jr., the Cubs could not complete the comeback, falling 5–4.
* April 29 – The Cubs, behind homers by Anthony Rizzo, Miguel Montero, and Ben Zobrist, came from behind to beat the Red Sox 7–4. The Cubs remained in first place in their division with a 13–10 record.
* April 30 – In the ESPN Sunday night game, the Cubs battled back from an early 2–0 deficit to tie the game in the seventh. However, Koji Uehara allowed three runs and Pedro Strop one run in the eighth as the Cubs lost to the Red Sox 6–2.

May

* May 1 – Brett Anderson lasted only innings as the Cubs were blown out 10–2 by the Philadelphia Phillies at Wrigley Field, losing their fourth game in the last five. The loss dropped the Cubs into a tie for the division lead with the Brewers, though the Cubs led by percentage points.
* May 2 – The Cubs beat the Phillies 8–3 with homers by Kris Bryant, Javier Báez, and Kyle Schwarber. Bryant also left the game late with tightness in his calf. Báez came within a double of hitting for the cycle, with four hits and three RBI. Jon Lester earned his first win of the season, allowing three runs in five innings.
* May 3 – The Cubs scored four times in the bottom of the sixth after trailing 3–1, highlighted by Willson Contreras' pinch-hit two-run double to take the lead. Contreras then scored from second on an infield hit by Matt Szczur to give the Cubs their fifth run of the game. Jake Arrieta got the win, 5–4 over the Phillies, but allowed two runs in the first inning as Cubs starting pitchers' ERA moved to 11.00 in the first inning.
* May 4 – Miguel Montero homered in the bottom of the eighth to tie the game at four and the Cubs won in the 13th on an error by Phillies' shortstop Freddy Galvas. Koji Uehara, the eighth Cub pitcher used in the game, got the win with a perfect 13th inning as Albert Almora Jr. scored on an error in the bottom of the 13th. The Cubs moved to 16–12 on the season. Starter John Lackey failed to pitch six innings for the first time on the season, pitching five-plus innings and allowing three runs.
* May 5 – Brett Gardner hit a three-run home run off of Héctor Rondón in the top of the ninth as the New York Yankees beat the Cubs 3–2 at Wrigley Field. Rondón, who was pitching in the ninth as closer Wade Davis was unavailable after pitching three days in a row, gave up the homer with two outs and two strikes on Gardner. Former Cub closer and current Yankee closer, Aroldis Chapman, got the save for the Yankees.
* May 6 – Brett Anderson, after getting knocked out in the second inning of his prior start, lasted only of an inning as he gave up five runs before leaving with soreness in his lower back. The Cub bullpen, trailing 6–0 after the first and needing a starter to go long because of recent use, could not hold the Yankees at six runs as the Cubs lost 11–6. Miguel Montero pitched a scoreless ninth for the Cubs.
* May 7 – The Cubs, trailing 4–1 going into the bottom of the ninth, scored three runs off former closer Aroldis Chapman to tie the game and force extra innings. Despite several chances to win the game, the Cubs fell 5–4 in 18 innings, getting swept by the Yankees. The game marked the longest interleague game in MLB history and had the most strikeouts, 48, in a game in MLB history. It was also only the second game ever where both teams had 20 or more strikeouts.
* May 9 – In the first game of a day-night doubleheader to due to a rainout of the first game of the series at Coors Field, the Colorado Rockies knocked Jake Arrieta out of the game in the fourth, scoring nine runs en route to a 10–4 win over the Cubs. The loss marked the Cubs fourth straight and dropped them to .500 on the season at 16–16.
* May 9 – In the nightcap of the doubleheader, the Cubs rebounded to win 8–1. John Lackey pitched seven strong innings without giving up a run and striking out 10 Rockies. Javier Báez and Kris Bryant homered as the Cubs moved to 17–16 on the season.
* May 10 – Following an almost one-hour rain delay, the Cubs were no-hit through six innings and were unable to push across a run, falling 3–0 to the Rockies. The loss left the Cubs with a 17–17 record on the season, having lost five of their previous six games, and in fourth place in the division, 2.5 games behind the Cardinals.
* May 12 – As the Cubs returned to St. Louis to face the first-place Cardinals, Eddie Butler was called up from the minors to pitch in Brett Anderson's vacated starting spot. Butler pitched six scoreless innings as the Cubs, behind Willson Contreras' two homers, beat the Cardinals 3–2. The win moved the Cubs within 1.5 games of the Cardinals for first place. Kris Bryant was a late scratch before the game due to an illness and his replacement, Jon Jay, left after two innings with back issues.
* May 13 – Looking to move within a half game of first, but short-handed with Bryant and Jay's issues, the Cubs called up highly touted rookie Ian Happ from AAA Iowa to make his major league debut. Happ homered in the seventh inning, but the Cards has already taken a 5–1 lead off Cub starter Jon Lester and the Cubs bullpen. The Cubs lost 5–3.

With the Cubs trailing by a run, Rizzo tripled in the sixth inning and was thrown at home trying to score on a Kris Bryant flyout. Rizzo collided with Padres catcher Austin Hedges, but Hedges held on to the ball to end the inning. Following the game, Rizzo's collision was questioned by Padres manager Andy Green as a dirty play. The Cubs would tie the game at two in the seventh with a Willson Contreras homer and would take the lead as Javier Báez scored following an error on an Albert Almora Jr. double giving the Cubs a 3–2 lead. Wade Davis pitched a stressful ninth, but was able to prevent the Padres from scoring the tying run as the Cubs won.

* June 26 – The Cubs traveled to Washington to take on the Nationals in a four-game set. In game one, Eddie Butler and five relievers combined to shut out the Nationals for eight innings.

The Cubs added four runs in the eighth and ninth innings to take a 5–1 lead into the bottom of the ninth. In the ninth, Héctor Rondón and Wade Davis gave up two runs apiece, but Davis struck out Ryan Zimmerman with the tying run on third and the winning run on second as the Cubs held on 5–4. Javier Báez made two great defensive plays in place of the injured Addison Russell.
* June 27 – Jake Arrieta and Miguel Montero struggled mightily attempting to contain Washington's running game as the Nationals stole seven bases against the combo and Arrieta allowed six runs in four-plus innings of work.

* June 28 – John Lackey gave up eight runs in innings of work on three homers as the Cubs were blown out 8–4. Kris Bryant left the game in the fifth after he turned an ankle catching a popup.

Division Series

On October 4, 2017, the Cubs announced that Kyle Hendricks would start Game 1 of the Division Series while Jon Lester would start Game 2. Joe Maddon also announced that José Quintana would start Game 3 and Jake Arrieta Game 4 (if necessary). On October 5, Nationals manager Dusty Baker announced that Stephen Strasburg would start Game 1 for the Nationals, but did not state who would start any other games. The Nationals later announced Gio González would start Game 2 while Max Scherzer would start Game 3. On October 8, Baker announced that Tanner Roark would start Game 4 for the Nationals.

Game 1

In Game 1 of the Division series, the Cubs faced the Nationals' Stephen Strasburg and were held hitless for five innings. Kyle Hendricks also shut out the Nationals, pitching seven shutout innings while allowing only two hits. In the sixth, Javier Báez reached on an error by Nationals' third basemen Anthony Rendon. Hendricks bunted him to second and, following a flyout by Ben Zobrist, Kris Bryant drove in Baez with a single to right to give the Cubs the 1–0 lead. Bryant, who advanced to second on the throw, was then driven in on a single by Anthony Rizzo to extend the lead to 2–0. The Cubs added to the lead on a Rizzo double following a Jon Jay double to push the lead to 3–0. Carl Edwards Jr. pitched a perfect eighth and Wade Davis slammed the door on the Nationals in the ninth as the Cubs took a 1–0 lead in the series.

Game 2

Looking to take a 2–0 lead in the series, the Cubs sent Jon Lester to the mound while the Nationals went with Gio González. Lester gave up a first inning home run to Anthony Rendon, but Willson Contreras quickly answered with a homer in the top of the second to tie the game at one. Anthony Rizzo gave the Cubs a 3–1 lead in the fourth when he homered to deep right with Kris Bryant at second. Lester cruised through the Nationals until the fifth inning with two outs and a runner on when he walked back-to-back batters to load the bases. However, Lester struck out Trea Turner to end the threat and would pitch a scoreless sixth. Pedro Strop pitched a scoreless seventh in relief and the Cubs looked to be in command as Carl Edwards Jr. took the hill in the eighth. Edwards gave up a pinch hit to Adam Lind but struck out Turner before Bryce Harper came to the plate. Harper crushed a hanging slider into the right field seats to tie the game at three. Edwards then walked Rendon and gave up a single to Daniel Murphy before being replaced by Mike Montgomery to face Ryan Zimmerman. Zimmerman homered just over the wall in left to give the Nationals a 6–3 lead heading into the ninth. In the ninth, Addison Russell singled with one out, but was wiped out on a game-ending double play grounder by Ben Zobrist. The loss moved the series to one game each as the series headed to Chicago for games three and four.

Game 3

As the series shifted to Wrigley Field, the Nationals sent their ace Max Scherzer to the mound while the Cubs countered with José Quintana. Quintana pitched well, but was not helped by his defense. Ben Zobrist committed an error on a grounder with a runner on in the third inning to put runners at the corners with two out. However, Quintana retired the next batter to escape the inning. In the sixth, with two outs, Kyle Schwarber dropped an easy fly ball that would have ended the inning and then kicked the ball allowing Daniel Murphy to reach third. Joe Maddon then lifted Quintana in favor of Pedro Strop. Strop, however, gave up a double to Ryan Zimmerman to give the Nationals the 1–0 lead. Meanwhile, Scherzer held the Cubs hitless until the seventh inning when Zobrist doubled with one out. Nationals manager Dusty Baker brought in Sammy Solis to pitch to Albert Almora Jr. who was pinch hitting for Schwarber. With a full count, Almora singled to left center to drive in Zobrist and tie the game. Jason Heyward followed with single, but was doubled off of first on Addison Russell's flyout to end the inning. Carl Edwards Jr., after struggling in Game 2, started the eighth, struck out Bryce Harper, and then retired the side. In the bottom of the eighth, Tommy La Stella pinch hit for Edwards and drew a walk from reliever Brandon Kintzler. He was then pinch run for by Leonys Martín as Jon Jay sacrificed Martín to second. Following a strikeout by Bryant, Baker brought in Óliver Pérez to face Anthony Rizzo. Rizzo, who said after the game that he expected to be walked with first base open and two outs, blooped a single to short left center that fell between three Nationals and scored Martín to give the Cubs the 2–1 lead. Wade Davis pitched a perfect ninth to close out the win and give the Cubs a 2–1 lead in the series.

Game 4

Game 4, originally scheduled to be played on October 10, was postponed to October 11 due to rain. The Cubs announced that Jake Arrieta would still pitch Game 4 despite the extra day off. Reports stated that the Nationals wanted Stephen Strasburg to pitch the game as he would be on normal rest. However, Strasburg declined stating that he was under the weather. However, hours before Game 4 was to begin, the Nationals announced that Strasburg would start. Jake Arrieta started for the Cubs and pitched well allowing only an unearned run on an error by Addison Russell in the third inning. Strasburg struck out 12 Cubs in his seven innings of work while not allowing a run. Arrieta left the game after four innings of work having thrown 90 pitches and trailing 1–0. Jon Lester relieved Arrieta and pitched 3.2 innings in relief, leaving in the eighth with a runner on first and two outs. Carl Edwards Jr. made his fourth relief appearance in the series and walked the next two Nationals he faced, loading the bases. Wade Davis then replaced Edwards and gave up a grand slam to Michael Taylor to stretch the Nationals lead to 5–0. The Cubs could manage nothing further and fell 5–0. The loss set the stage for a deciding Game 5 in Washington the next day with the series tied at two.

Game 5

As the teams returned to Washington for the deciding Game 5, the Cubs sent Game 1 starter Kyle Hendricks to the mound while the Nationals started Gio González. The Cubs started the scoring in the first as Jon Jay led off the game with a double and scored on an Anthony Rizzo groundout. The Cubs then loaded the bases with two outs in the first, but Jason Heyward grounded out to end the threat. In the second inning, Daniel Murphy homered and Michael Turner hit a three-run homer to put the Nationals up 4–1. González continued to struggle in the third as Kris Bryant doubled and Willson Contreras and Albert Almora Jr. walked to the load the bases. Addison Russell drove in his first run of the night on a groundout and Contreras scored on a wild pitch to narrow the lead to 4–3. Heyward would again end the threat by striking out. The Nationals went to the pen in the fourth and in the fifth brought in starter Max Scherzer. After Bryant and Rizzo were retired by Scherzer, seven straight Cubs batters reached base, scoring four runs, two on a double by Russell, to give the Cubs the lead 7–4. The Cubs added to their lead in the sixth as Russell doubled in Ben Zobrist on a fly ball that was misplayed by Jayson Werth. The Cubs went to the bullpen in the bottom of the fifth and in the sixth the Nationals added two runs on a wild pitch by Mike Montgomery which scored a run and a double by Murphy. Leading 8–6 in the seventh, the Cubs added another run when Kyle Schwarber pinch hit and doubled, scoring on a groundout by Kris Bryant. The Nationals answered in the seventh as the Cubs used Carl Edwards Jr. and José Quintana to get two outs, but a sacrifice fly by Bryce Harper narrowed the lead to 9–7. Wade Davis came in for the Cubs to get a seven-out save and struck out Ryan Zimmerman to end the inning. In the eighth, Davis gave up a run-scoring single by Taylor to bring the lead to one at 9–8. Following a single by José Lobatón to put runners on first and second with two outs, Contreras picked Lobatón off of first to end the inning. In the ninth, Davis set the Nationals down in order, striking out Werth and Harper to end the game and win the series for the Cubs.

Championship Series

Game 1

As the Cubs traveled to Los Angeles for Game 1 of the Championship Series, their flight was forced to make an emergency landing in Albuquerque, New Mexico as José Quintana's wife suffered a medical issue. The Cubs were on the ground for five hours before continuing on to Los Angeles, Quintana joined the team later that day. Quintana was named the starting pitcher despite this issue and pitched well for the Cubs. Albert Almora Jr. gave the Cubs the lead in the fourth on a two-run home run off Dodger starter Clayton Kershaw. The Dodgers answered in the fifth on an RBI double by Yasiel Puig and a sacrifice fly by Charlie Culberson. Quintana left after five innings and Héctor Rondón, who had replaced Justin Wilson on the Championship Series roster, gave up a home run to Chris Taylor in the sixth to give the Dodgers a 3–2 lead. Puig homered off Mike Montgomery in the seventh and Justin Turner drove in a run to stretch the Dodger lead to 5–2. The Cubs managed nothing against the Dodger bullpen which relieved Kershaw after five innings as the Cubs fell behind in the series 1–0.

Game 2

In Game 2, the Cubs sent Jon Lester to the mound on short rest after pitching 3.2 innings in relief in Game 4 of the NLDS. Addison Russell homered off Rich Hill in the fifth to give the Cubs a 1–0 lead, but the Dodger tied it in the bottom half of the fifth on a Culberson double and a Justin Turner single. As the game went to the bullpens after five innings, the Cubs were again shut out, managing only a hit-by-pitch of Anthony Rizzo. In the bottom of the ninth, Yasiel Puig led off with a walk off of Brian Duensing. A sacrifice bunt moved him to second, but Duensing struck out Kyle Farmer for the second out. Joe Maddon then lifted Duensing to bring in usual starting pitcher John Lackey. Lackey, who had pitched 1.2 innings in relief the day before, had never pitched on back-to-back days in his career. He walked the first batter he faced and then gave up a three-run, game-winning home run to Turner to give the Dodgers the 4–1 win and a 2–0 lead in the series.

Game 3

As the series shifted to Wrigley Field with the Cubs in an 0–2 hole, Kyle Hendricks looked to keep the Cubs in the series. Kyle Schwarber homered in the first inning to give the Cubs a 1–0 lead, but solo home runs in the second and third innings gave the Dodgers the lead. Hendricks was lifted in the sixth with two runners on and trailing 3–1, but a walk to Dodger starting pitcher Yu Darvish by Carl Edwards Jr. with the bases loaded moved the score to 4–1. The Dodgers added two more runs in the eighth on a wild pitch by Mike Montgomery and a sacrifice fly to increase the lead to 6–1. Albert Almora Jr. and Alex Avila singled and doubled in the ninth to put runners on second and third with no outs, but Dodger closer Kenley Jansen retired the next three batters to end the game. The loss moved the Cubs to brink of elimination, trailing in the series 3–0.

Game 4

Looking to stave off elimination, the Cubs sent Jake Arrieta to the mound against Dodger starter Alex Wood who had not yet appeared in the postseason. The Cubs started the scoring in the second on a 491-foot home run by Willson Contreras and, in his first hit in the postseason, Javier Báez also homered to give the Cubs a 2–0 lead in the second inning. The Dodgers answered immediately as Cody Bellinger hit a solo shot in the top of the third to cut the lead in half. Báez homered again in the fifth to extend the lead to 3–1. Arrieta pitched well, allowing only one run in 6.2 innings of work and left with two runners on in the seventh, but Brian Duensing retired the only batter he faced to end the inning. Wade Davis entered in the eighth for a two-inning save and promptly gave up a home run to Justin Turner, reducing the lead to 3–2. After two walks and an overturned strike three call that led to Joe Maddon being ejected, Davis was able to get out of the inning. In the ninth, Davis struck out Austin Barnes before walking Chris Taylor. Davis was able to induce Bellinger to hit into a game-ending double play to give the Cubs the win and extend the series to Game 5.

Game 5

The Dodgers scored first on an RBI hit by Cody Bellinger, followed by a second inning home run by Enrique Hernández. He would hit two more home runs later in the game; a grand slam in the third and two-run homer in the ninth. He became the fourth Dodger player to hit a postseason grand slam (joining Ron Cey and Dusty Baker from the 1977 NLCS and James Loney in the 2008 NLDS which was also against the Cubs). His seven RBIs were also a NLCS record. Chris Taylor and Justin Turner were voted co-MVPs of the series. The lone Chicago run came on a Kris Bryant home run in the fourth. Every Cubs run scored in the series came via a home run. With the 11–1 victory the Dodgers returned to the World Series for the first time since 1988.
