Defense-Independent Component ERA
Defense-Independent Component ERA (DICE) is a 21st-century variation on Component ERA, one of an increasing number of baseball sabermetrics that fall under the umbrella of defense independent pitching statistics. DICE was created by Clay Dreslough in 2001. The formula for Defense-Independent Component ERA (DICE) is: : \text =3.00 + \frac In that equation, "HR" is home runs, "BB" is walks, "HBP" is hit batters, "K" is strikeouts, and "IP" is innings pitched. That equation gives a number that is better at predicting a pitcher's ERA in the following year than the pitcher's actual ERA in the current year. Component ERA was created by Bill James to create a more accurate way of evaluating pitchers than earned run average (ERA). Whereas ERA is significantly affected by luck (such as whether the component hits are allowed consecutively), Component ERA eliminates this factor and assigns a weight to each of the recorded 'components' of a pitchers performance. For CERA, these are single ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 that walks and ...

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 hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabermetrics
Sabermetrics, or originally SABRmetrics, is the empirical analysis of baseball, especially baseball statistics that measure in-game activity. Sabermetricians collect and summarize the relevant data from this in-game activity to answer specific questions. The term is derived from the acronym SABR, which stands for the Society for American Baseball Research, founded in 1971. The term "sabermetrics" was coined by Bill James, who is one of its pioneers and is often considered its most prominent advocate and public face. Early history Henry Chadwick, a sportswriter in New York, developed the box score in 1858. This was the first way statisticians were able to describe the sport of baseball by numerically tracking various aspects of game play. The creation of the box score has given baseball statisticians a summary of the individual and team performances for a given game. Sabermetrics research began in the middle of the 20th century with the writings of Earnshaw Cook, one of the ea ... [...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 ... [...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 ...

Single (baseball)
In baseball, a single is the most common type of base hit, accomplished through the act of a batter safely reaching first base by hitting a fair ball (thus becoming a runner) and getting to first base before a fielder puts him out. As an exception, a batter-runner reaching first base safely is not credited with a single when an infielder attempts to put out another runner on the first play; this is one type of a fielder's choice. Also, a batter-runner reaching first base on a play due to a fielder's error trying to put him out at first base or another runner out (as a fielder's choice) is not credited with a single. On a single hit to the outfield, any runners on second base or third base normally score, and sometimes the runner from first base is able to advance to third base. Depending on the location of the hit, a quick recovery by the outfielder can prevent such an advance or create a play on the advancing runner. Hitters who focus on hitting singles rather than dou ...

Double (baseball)
In baseball, a double is the act of a batter striking the pitched ball and safely reaching second base without being called out by the umpire, without the benefit of a fielder's misplay (see error) or another runner being put out on a fielder's choice. A double is a type of hit (the others being the single, triple and home run) and is sometimes called a "two-bagger" or "two-base hit". For statistical and scorekeeping purposes it is denoted by 2B. Description Typically, a double is a well-hit ball into the outfield that finds the "gap" between the center fielder and one of the corner outfielders, bounces off the outfield wall and down into the field of play, or is hit up one of the two foul lines. To hit many doubles, a batter must have decent hitting skill and power; it also helps to run well enough to beat an outfield throw. Doubles typically drive in runs from third base, second base, and even from first base at times. When total bases and slugging percentages ...

Triple (baseball)
In baseball, a triple is the act of a Batter (baseball), batter safely reaching third base after hitting the ball, with neither the benefit of a fielder's misplay (see error (baseball statistics), error) nor another baserunner, runner being put out on a fielder's choice. A triple is sometimes called a "three-bagger" or "three-base hit". For baseball statistics, statistical and baseball scorekeeping, scorekeeping purposes it is denoted by 3B. Triples have become somewhat rare in Major League Baseball, less common than both the Double (baseball), double and the home run. This is because it requires a ball to be hit solidly to a distant part of the field (ordinarily a line drive or Fly ball (baseball), fly ball near the Foul line (baseball), foul line closest to Right fielder, right field), or the ball to take an irregular bounce in the outfield, usually against the wall, away from a outfielder, fielder. It also requires the batter's team to have a good strategic reason for wanting ... [...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 ...

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.
