Defense-Independent ERA
In baseball statistics, Defense-Independent ERA (dERA), created by Voros McCracken, projects what a pitcher's earned run average (ERA) would have been, if not for the effects of defense and luck on the actual games in which he pitched. Method Version 2.0 of dERA uses the following statistics: * Batters Faced (BFP) * Home Runs Allowed (HR) * Total Walks Allowed (BB) * Intentional Walks Allowed (IBB) * Strikeouts (K) * Hit Batsmen (HB) 0) Multiply BFP by 0.0074 to get the number of intentional walks allowed (dIBB). 1) Divide HB by BFP-IBB. Call this $HB. Then multiply $HB by BFP-dIBB. This number gives the DIPS number of Hit Batsmen (dHB). 2) Divide (BB-IBB) by (BFP-IBB-HB), and call this number $BB. Multiply BFP by 0.0074, and call this dIBB. :2a) Then multiply $BB by (BFP-dIBB-dHB). Take this number and add IBB. This number is now the DIPS number of total walks allowed (dBB). 3) Divide K by (BFP-HB-BB) and call this number $K. Remember this number for later. :3a) Multiply $K by ...

Baseball Statistics
Baseball statistics play an important role in evaluating the progress of a player or team. Since the flow of a baseball game has natural breaks to it, and normally players act individually rather than performing in clusters, the sport lends itself to easy record-keeping and statistics. Statistics have been kept for professional baseball since the creation of the National League and American League, now part of Major League Baseball. Many statistics are also available from outside Major League Baseball, from leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency of whether these records were kept, of the standards with respect to which they were calculated, and of their accuracy has varied. Development The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick. Based on his experience with the sport of cricket, Chadwick devised the predecessors to modern-day statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voros McCracken
Robert "Voros" McCracken (born August 17, 1971, Chicago) is an American baseball sabermetrician. "Voros" (vörös in hungarian = red in english) is a nickname from his partial Hungarian heritage. He is widely recognized for his pioneering work on Defense Independent Pitching Statistics (DIPS). DIPS McCracken first published his ideas about DIPS in 1999 on the rec.sports.baseball newsgroup on Usenet. He also effectively named the new concept of "defense independent pitching" with that publication: "I've been working on a pitching evaluation tool and thought I'd post it here to get some feedback. I call it 'Defensive Independent Pitching' and what it does is evaluate a pitcher base strictly on the statistics his defense has no ability to affect...". His findings implied that major league pitchers had little control over the outcome of balls put into play against them and specifically that the percentage of balls put into play against a particular pitcher that fell for hits did not ...

Earned Run Average
In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Thus, a lower ERA is better. Runs resulting from passed balls or defensive errors (including pitchers' defensive errors) are recorded as unearned runs and omitted from ERA calculations. Origins Henry Chadwick is credited with devising the statistic, which caught on as a measure of pitching effectiveness after relief pitching came into vogue in the 1900s. Prior to 1900—and, in fact, for many years afterward—pitchers were routinely expected to pitch a complete game, and their win–loss record was considered sufficient in determining their effectiveness. After pitchers like James Otis Crandall and Charley Hall made names for themselves as relief specialists, gauging a pitcher's e ...

Total Batters Faced
In baseball statistics, Batters Faced (BF), also known as Total Batters Faced (TBF) or Batters Facing Pitcher (BFP) is the number of batters who made a plate appearance before the pitcher in a game or in a season. For a given game, the number of plate appearances for an offense is 3×(Innings) + (Runs scored) + (Runners left on base). Major league records The major league record for batters faced in a career belongs to Cy Young, who faced 29,565 batters between 1890 and 1911. Will White of the Cincinnati Reds holds the single season record; he faced 2,906 batters in 1879. The last pitcher to face 1,500 or more batters in a single season was Wilbur Wood of the 1973 Chicago White Sox. On May 1, 1920, Leon Cadore of the Brooklyn Robins faced 96 Boston Braves batters, an MLB single game record dating back to at least 1901. Oakland's Steve McCatty is the last pitcher to face 50 or more batters in a game. McCatty pitched to 51 batters in a 14-inning complete game loss to the Seattl ...

Home Runs Allowed
In baseball statistics, home runs allowed (HRA) signifies the total number of home runs a pitcher allowed. The Major League Baseball record for the most home runs allowed by any pitcher belongs to Jamie Moyer (522 in his career). He gave up home runs while pitching for eight different teams across both leagues. Warren Spahn gave up the most National League home runs (434) and the American League record is 422, held by Frank Tanana Frank Daryl Tanana (born July 3, 1953) is an American former professional baseball left-handed pitcher. In a Major League Baseball career that stretched from 1973 to 1993, he pitched for the California Angels, Boston Red Sox, Texas Rangers, De .... The Minnesota Twins' Bert Blyleven set Major League Baseball's season record in 1986, allowing a total of 50 home runs to opposing batters.

Base On Balls
A base on balls (BB), also known as a walk, occurs in baseball when a batter receives four pitches that the umpire calls '' balls'', and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). It is considered a faux pas for a professional player to literally walk to first base; the batter-runner and any advancing runners normally jog on such a play. The term "base on balls" distinguishes a walk from the other manners in which a batter can be awarded first base without liability to be put out (e.g., hit by pitch (HBP), catcher's interference). Though a base on balls, catcher's interference, or a batter hit by a pitched ball all result in the batter (and possibly runners on base) being awarded a base, the term "walk" usually refers only to a base on balls, and not the other methods of reaching base without the bat touching the ball. An importan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intentional Base On Balls
In baseball, an intentional base on balls, usually referred to as an intentional walk and denoted in baseball scorekeeping by ''IBB'', is a walk issued to a batter by a pitcher with the intent of removing the batter's opportunity to swing at the pitched ball. A pitch that is intentionally thrown far outside the strike zone for this purpose is referred to as an ''intentional ball''. Beginning with the 2017 season, Major League Baseball has removed the requirement to throw four intentional balls. In MLB and in amateur baseball, such as high school and college games, and in most levels of Little League Baseball, the manager of the team on the field now simply asks the plate umpire to let the batter go to first base. Strategy The purpose of an intentional walk is to bypass the current batter in order to face the following batter, whom the defensive team expects to be easier to put out. The risk to the fielding team issuing an intentional walk is that they turn the batter into a bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strikeout
In baseball or softball, a strikeout (or strike-out) occurs when a batter accumulates three strikes during a time at bat. It usually means that the batter is out. A strikeout is a statistic recorded for both pitchers and batters, and is denoted by K in scorekeeping and statistics. A "strikeout looking" — in which the batter does not swing and the third strike is called by the umpire — is usually denoted by a ꓘ. Although a strikeout suggests that the pitcher dominated the batter, the free-swinging style that generates home runs also leaves batters susceptible to striking out. Some of the greatest home run hitters of all time—such as Alex Rodriguez, Reggie Jackson, and Jim Thome—were notorious for striking out. Rules and jargon A pitched ball is ruled a ''ball'' by the umpire if the batter did not swing at it and, in that umpire's judgement, it does not pass through the strike zone. Any pitch at which the batter swings unsuccessfully or, that in that umpire's judg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hit By Pitch
In baseball, hit by pitch (HBP) is an event in which a batter or his clothing or equipment (other than his bat) is struck directly by a pitch from the pitcher; the batter is called a hit batsman (HB). A hit batsman is awarded first base, provided that (in the plate umpire's judgment) he made an honest effort to avoid the pitch, although failure to do so is rarely called by an umpire. Being hit by a pitch is often caused by a batter standing too close to, or "crowding", home plate. The rule dates from 1884; before that, a pitch that struck the batter was merely a ball. Official rule Per baseball official rule 5.05(b), a batter becomes a baserunner and is awarded first base when he or his equipment (except for his bat): *is touched by a pitched ball outside the strike zone, *''and'' he attempts to avoid it (or had no opportunity to avoid it), *''and'' he did not swing at the pitch. If all these conditions are met, the ball is dead, and other baserunners advance if they are forced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earned Run
In baseball, an earned run is any run that was fully enabled by the offensive team's production in the face of competent play from the defensive team. Conversely, an unearned run is a run that would not have been scored without the aid of an error or a passed ball committed by the defense. An unearned run counts just as much as any other run for the purpose of determining the score of the game. However, it is "unearned" in that it was, in a sense, "given away" by the defensive team. Both total runs and earned runs are tabulated as part of a pitcher's statistics. However, earned runs are specially denoted because of their use in calculating a pitcher's earned run average (ERA), the number of earned runs allowed by the pitcher per nine innings pitched (i.e., averaged over a regulation game). Thus, in effect, the pitcher is held personally accountable for earned runs, while the responsibility for unearned runs is shared with the rest of the team. To determine whether a run ...

Component ERA
Component ERA or ERC is a baseball statistic invented by Bill James. It attempts to forecast a pitcher's earned run average (ERA) from the number of hits and walks allowed rather than the standard formula of average number of earned runs per nine innings. ERC allows one to take a fresh look at a pitcher's performance and gauge if his results are more or less than the sum of its parts. The formula for ERC as it appears in the 2004 edition of the Bill James Handbook: ERC = 9 * - 0.56 where H is hit (baseball), hits, BB is bases on balls (walks), HBP is hit by pitch, BFP is batters faced by pitcher, IP is innings pitched, and PTB is pitcher's total bases and is defined as: PTB = 0.89 * (1.255*(H-HR) + 4*HR) + 0.56 * (BB + HBP -IBB) where HR is home runs, IBB is intentional walks, and others are as above. The point of the first component is to represent the number of baserunners allowed. The PTB component combines an estimate of extra bases allowed (first half) with the fact t ...
