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 ...

Baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill James
George William James (born October 5, 1949) is an American baseball writer, historian, and statistician whose work has been widely influential. Since 1977, James has written more than two dozen books devoted to baseball history and statistics. His approach, which he termed sabermetrics in reference to the Society for American Baseball Research (SABR), scientifically analyzes and studies baseball, often through the use of statistical data, in an attempt to determine why teams win and lose. In 2006, ''Time'' named him in the ''Time'' 100 as one of the most influential people in the world. In 2003, James was hired as senior advisor on Baseball Operations for the Boston Red Sox and worked for the team for 17 years during which they won four World Series championships. Early life James was born in Holton, Kansas; his mother died in 1954 when he was five. His father was a janitor and a handyman. After four years at the University of Kansas (KU) residing at Stephenson Scholarship H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hit (baseball)
In baseball statistics, a hit (denoted by H), also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice. Scoring a hit To achieve a hit, the batter must reach first base before any fielder can either tag him with the ball, throw to another player protecting the base before the batter reaches it, or tag first base while carrying the ball. The hit is scored the moment the batter reaches first base safely; if he is put out while attempting to stretch his hit to a double or triple or home run on the same play, he still gets credit for a hit (according to the last base he reached safely on the play). If a batter reaches first base because of offensive interference by a preceding runner (including if a preceding runner is hit by a batted ball), he is also credited with a hit. Types of hits A hit for one base is called a single, for two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bases 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] |
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] |
Batters Faced By Pitcher
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 Seattle ...

Innings Pitched
In baseball, innings pitched (IP) are the number of innings a pitcher has completed, measured by the number of batters and baserunners that are put out while the pitcher is on the pitching mound in a game. Three outs made is equal to one inning pitched. One out counts as one-third of an inning, and two outs counts as two-thirds of an inning. Sometimes, the statistic is written 34.1, 72.2, or 91.0, for example, to represent innings, innings, and 91 innings exactly, respectively. Runners left on base by a pitcher are not counted in determining innings pitched. It is possible for a pitcher to enter a game, give up several hits and possibly even several runs, and be removed before achieving any outs, thereby recording a total of zero innings pitched. Alternatively, it is possible for a pitcher to enter a situation where there are two runners on base and no outs. He could throw one pitch that results in a triple play, and for that one pitch he would be credited with a full inning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Run
In baseball, a home run (abbreviated HR) is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home plate safely in one play without any errors being committed by the defensive team. A home run is usually achieved by hitting the ball over the outfield fence between the foul poles (or hitting either foul pole) without the ball touching the field. Far less common is the "inside-the-park" home run where the batter reaches home safely while the baseball is in play on the field. When a home run is scored, the batter is credited with a hit and a run scored, and a run batted in ( RBI) for each runner that scores, including himself. Likewise, the pitcher is recorded as having given up a hit and a run, with additional runs charged for each runner that scores other than the batter. Home runs are among the most popular aspects of baseball and, as a result, prolific home run hitters are usually the most popular among fans and consequently th ...

Intentional Walk
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 ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
