Wins Above Replacement
Wins Above Replacement or Wins Above Replacement Player, commonly abbreviated to WAR or WARP, is a non-standardized sabermetric baseball statistic developed to sum up "a player's total contributions to his team". A player's WAR value is claimed to be the number of additional wins his team has achieved above the number of expected team wins if that player were substituted with a replacement-level player: a player who may be added to the team for minimal cost and effort. Individual WAR values are calculated from the number and success rate of on-field actions by a player (in batting, baserunning, fielding, and pitching), with higher values reflecting larger contributions to a team's success. Schoenfield: 2012 WAR value also depends on what position a player plays, with more value going to key defensive positions like catcher and shortstop than positions with less defensive importance such as first base. A high WAR value built up by a player reflects successful performance, a large ... [...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] |
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 ...

Catcher
Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the ( home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket. Positioned behind home plate and facing toward the outfield, the catcher can see the whole field, and is therefore in the best position to direct and lead the other players in a defensive play. The catcher typically calls for pitches using hand signals. The calls are based on the pitcher's mechanics and strengths, as well as the batter's tendencies and weaknesses. Essentially, the catcher controls what happens during the game when the ball is not "in play". Foul tips, bouncing balls in the dirt, and contact with runners during plays at the plate are all events to be handl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ineffectiveness, injury, or 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 closers, setup men, middle relief pitchers, left/right-handed specialists, and long relievers. Whereas starting pitchers usually 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 metonymically as a team's bullpen, which refers to the area where the relievers sit during games, and where they warm-up prior to entering the game.

Outfielder
An outfielder is a person playing in one of the three defensive positions in baseball or softball, farthest from the batter. These defenders are the left fielder, the center fielder, and the right fielder. As an outfielder, their duty is to catch fly balls and ground balls then to return them to the infield for the out or before the runner advances, if there are any runners on the bases. As an outfielder, they normally play behind the six players located in the field. By convention, each of the nine defensive positions in baseball is numbered. The outfield positions are 7 (left field), 8 (center field) and 9 (right field). These numbers are shorthand designations useful in baseball scorekeeping and are not necessarily the same as the squad numbers worn on player uniforms. Outfielders named to the MLB All-Century Team are Hank Aaron, Ty Cobb, Joe DiMaggio, Mickey Mantle, Willie Mays, Stan Musial, Pete Rose, Babe Ruth, Ted Williams and Ken Griffey Jr. Strategy Pl ...

Glossary Of Baseball (R)
R rabbit ears :Indicates a participant in the game who hears things perhaps too well for their own good. A player who becomes nervous or chokes when opposing players or fans yell at or razz them is said to have rabbit ears. Also, an umpire who picks up on every complaint hurled at them from the dugouts is described this way. rag arm :A player, typically a pitcher, with a weak arm. "I hope the Cubs did not give up an actual Major League player for this rag-arm home-run machine." railroad :To run into and knock over the catcher when running home from third base, or to run into a first-baseman when running from home to first. In either case, neither the catcher nor the first baseman may be able to duck out of the way because he must play the ball and stay in position in order to make an out. rain delay :Rain ''delay'' refers to situations when a game starts late due to rain or is temporarily suspended due to rain.

Inning
In baseball, softball, and similar games, an inning is the basic unit of play, consisting of two halves or frames, the "top" (first half) and the "bottom" (second half). In each half, one team bats until three outs are made, with the other team playing defense. A full baseball game is typically scheduled for nine innings, while softball games consist of seven innings; although this may be shortened due to weather or extended if the score is tied at the end of the scheduled innings. The use of the term ''inning'' in baseball and softball contrasts with cricket and rounders, in which the term is '' innings'' in both singular and plural. Gameplay Each half-inning formally starts when the umpire calls "Play" or "Play ball". A full inning consists of six outs, three for each team; and, in Major League Baseball and most other adult leagues, a regulation game consists of nine innings. The visiting team bats in the first half-inning, the ''top'' of the inning, derived from the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plate Appearance
In baseball statistics, a player is credited with a plate appearance (denoted by PA) each time he completes a turn batting. Under Rule 5.04(c) of the Official Baseball Rules, a player completes a turn batting when he is put out or becomes a runner. This happens when he strikes out or is declared out before reaching first base; or when he reaches first base safely or is awarded first base (by a base on balls, hit by pitch, catcher's interference, or obstruction); or when he hits a fair ball which causes a preceding runner to be put out for the third out before he himself is put out or reaches first base safely (''see also'' left on base, fielder's choice, force play). A very similar statistic, at bats, counts a subset of plate appearances that end under certain circumstances. Use as batting record qualifier While at bats are used to calculate batting averages, slugging percentages, plate appearances have no such statistical value. However, at season's end, a player mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultimate Zone Rating
Ultimate zone rating (UZR) is a sabermetric statistic used to measure fielding. It compares the event that actually happened (hit/out/error) to data on similarly hit balls in the past to determine how much better or worse the fielder did than the "average" player. UZR divides a baseball field into multiple zones and assigns individual fielders responsibility for those zones. UZR calculations are provided at FanGraphs by Mitchel Lichtman. Proponents of the statistic advise that defense is best judged over three-year spans, as a given year contains a relatively small sample and can result in large statistical swings. Former Major League Baseball shortstop David Eckstein says "a lot of defense is putting yourself in the right position to make plays." Josh Stein, San Diego Padres The San Diego Padres are an American professional baseball team based in San Diego. The Padres compete in Major League Baseball (MLB) as a member club of the National League (NL) West division. Founded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WOBA
In baseball, wOBA ( /'woʊbə/, or weighted on-base average) is a statistic, based on linear weights, designed to measure a player's overall offensive contributions per plate appearance. It is formed from taking the observed run values of various offensive events, dividing by a player's plate appearances, and scaling the result to be on the same scale as on-base percentage. Unlike statistics like OPS, wOBA attempts to assign the proper value for each type of hitting event. It was created by Tom Tango and his coauthors for ''The Book: Playing the Percentages in Baseball''. Usage In 2008, sabermetrics website FanGraphs began listing the current and historical wOBA for all players in Major League Baseball. It forms the basis of the offensive component of their wins above replacement (WAR) metric. Sites such as The Hardball Times have studied wOBA and found it to perform comparably to or better than other similar tools ( OPS, RC, etc.) used in sabermetrics to estimate runs. '' ...

Baseball Positions
In the sport of baseball, each of the nine players on a team is assigned a particular fielding position when it is their turn to play defense. Each position conventionally has an associated number, for use in scorekeeping by the official scorer: 1 ( pitcher), 2 (catcher), 3 ( first baseman), 4 ( second baseman), 5 ( third baseman), 6 (shortstop), 7 ( left fielder), 8 (center fielder), and 9 (right fielder). Collectively, these positions are usually grouped into three groups: the outfield (left field, center field, and right field), the infield (first base, second base, third base, and shortstop), and the battery (pitcher and catcher). Traditionally, players within each group will often be more able to exchange positions easily (that is, a second baseman can usually play shortstop well, and a center fielder can also be expected to play right field); however, the pitcher and catcher are highly specialized positions and rarely will play at other positions.
