Relief Pitcher
In baseball and softball, a relief pitcher or reliever is a pitcher who enters the game after the starting pitcher is removed because of fatigue (medical), fatigue, ineffectiveness, injury, or ejection (sports), ejection, or for other strategic reasons, such as inclement weather delays or pinch hitter substitutions. Relief pitchers are further divided informally into various roles, such as Closer (baseball), closers, setup men, middle relief pitchers, left-handed specialist, left/right-handed specialists, and long relievers. Whereas starting pitchers usually pitch count, throw so many pitches in a single game that they must rest several days before pitching in another, relief pitchers are expected to be more flexible and typically pitch in more games with a shorter time period between pitching appearances but with fewer innings pitched per appearance. A team's staff of relievers is normally referred to Metonymy, metonymically as a team's bullpen, which refers to the area where th ...

Tommy John Surgery
Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery (TJS), is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor. The procedure is common among collegiate and professional athletes in several sports, particularly in baseball. The procedure was devised in 1974 by orthopedic surgeon Frank Jobe, a Los Angeles Dodgers team physician who served as a special advisor to the team until his death in 2014. It is named after the first baseball player to undergo the surgery, major league pitcher Tommy John, whose record of 288 career victories ranks seventh among left-handed pitchers. The initial operation, John's successful post-surgery career, and the relationship between the two men was the subject of a 2013 ESPN ''30 for 30'' documentary. Uses The ulnar collateral ligament (UCL) can become stretched, frayed or torn thr ...

Major League Baseball
Major League Baseball (MLB) is a professional baseball organization and the oldest major professional sports league in the world. MLB is composed of 30 total teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. The NL and AL were formed in 1876 and 1901, respectively. Beginning in 1903, the two leagues signed the National Agreement and cooperated but remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan. It is also included as one of the major professional sports leagues in the United States and Canada. Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869. Before that, some teams had secretly paid certain players. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one te ...

Changeup
A changeup is a type of pitch in baseball and fastpitch softball. The changeup is a staple off-speed pitch often used in a pitcher's arsenal, usually thrown to look like a fastball but arriving much more slowly to the plate. Its reduced speed coupled with its deceptive delivery is meant to confuse the batter's timing. It is meant to be thrown the same as a fastball, but farther back in the hand, which makes it release from the hand slower while still retaining the look of a fastball. A changeup is generally thrown to be 8–15 miles per hour slower than a fastball. If thrown correctly, the changeup will confuse the batter because the human eye cannot discern that the ball is coming significantly slower until it is around 30 feet from the plate. For example, a batter swings at the oncoming ball as if it were a 90 mph fastball, but instead the ball is coming in at 75 mph—this means they will be swinging too early to hit the ball well (also known as being "way out in f ...

Curveball
In baseball and softball, the curveball is a type of pitch thrown with a characteristic grip and hand movement that imparts forward spin to the ball, causing it to dive as it approaches the plate. Varieties of curveball include the 12–6 curveball, power curveball, and the knuckle curve. Its close relatives are the slider and the slurve. The "curve" of the ball varies from pitcher to pitcher. The expression "to throw a curveball" essentially translates to introducing a significant deviation to a preceding concept. Grip and action The curveball is gripped much like a cup or drinking glass is held. The pitcher places the middle finger on and parallel to one of the long seams, and the thumb just behind the seam on the opposite side of the ball such that if looking from the top down, the hand should form a "C shape" with the horseshoe pointing in towards the palm following the contour of the thumb. The index finger is placed alongside the middle finger, and the other two extran ...

Fastball
The fastball is the most common type of pitch thrown by pitchers in baseball and softball. "Power pitchers," such as former American major leaguers Nolan Ryan and Roger Clemens, rely on speed to prevent the ball from being hit, and have thrown fastballs at speeds of (officially) and up to (unofficially). Pitchers who throw more slowly can put movement on the ball, or throw it on the outside of home plate where batters can't easily reach it. Fastballs are usually thrown with backspin, so that the Magnus effect creates an upward force on the ball. This causes it to fall less rapidly than expected, and sometimes causes an optical illusion often called a rising fastball. Although it is impossible for a human to throw a baseball fast enough and with enough backspin for the ball to actually rise, to the batter the pitch seems to rise due to the unexpected lack of natural drop on the pitch. A straight pitch is achieved by gripping the ball with the fingers across the wide part o ...

Triple-A West
The Pacific Coast League (PCL) is a Minor League Baseball league that operates in the Western United States. Along with the International League, it is one of two leagues playing at the Triple-A level, which is one grade below Major League Baseball (MLB). The PCL was one of the premier regional baseball leagues in the first half of the 20th century. Although it was never recognized as a true major league, to which it aspired, its quality of play was considered very high. A number of top stars of the era, including Joe DiMaggio and Ted Williams, were products of the league. In 1958, with the arrival of major league teams on the west coast and the availability of televised major league games, the PCL's modern era began with each team signing Player Development Contracts to become farm teams of major league clubs. Following MLB's reorganization of the minor leagues in 2021, it operated as the Triple-A West for one season before switching back to its previous moniker in 2022. A l ...

40-man Roster
A Major League Baseball roster is a list of players who are allowed, by league agreement, to play for a Major League Baseball (MLB) team. Each MLB team maintains two rosters: an active roster of players eligible to participate in an MLB game, and an expanded roster encompassing the active roster plus additional reserve players. Beginning with the , the active roster size is 26 players, and the expanded roster size is 40 players (the expanded roster is commonly referred to as the "40-man roster").

With exceptions through the years for varying economic conditions (primarily during World War I, the Great Depression, post-World War ...
