Speed Score
Speed Score, often simply abbreviated to Spd, is a statistic used in Sabermetric studies to evaluate a baseball player's speed. It was invented by Bill James, and first appeared in the 1987 edition of the ''Bill James Baseball Abstract''. Speed score is on a scale of 0 to 10, with zero being the slowest and ten being the fastest. League average is generally around 4.5. Formula Speed Score is calculated using six factors: stolen base percentage, stolen base attempts as a percentage of opportunities, triples, double plays grounded into as a percentage of opportunities, runs scored as a percentage of times on base, and defensive position and range. Factors The individuals factors are calculated as follows: Factor 1 (Stolen base percentage): :\mathit = 20 \cdot \left( - 0.4\right) Where SB= stolen bases and CS= caught stealings. Factor 2 (Stolen base attempts): :\mathit = \cdot \sqrt Where 1B=singles, BB= walks and HBP= hit by pitch. Factor 3 (Triples): :\mathit = 625 \cdot ...

Statistic
A statistic (singular) or sample statistic is any quantity computed from values in a sample which is considered for a statistical purpose. Statistical purposes include estimating a population parameter, describing a sample, or evaluating a hypothesis. The average (or mean) of sample values is a statistic. The term statistic is used both for the function and for the value of the function on a given sample. When a statistic is being used for a specific purpose, it may be referred to by a name indicating its purpose. When a statistic is used for estimating a population parameter, the statistic is called an ''estimator''. A population parameter is any characteristic of a population under study, but when it is not feasible to directly measure the value of a population parameter, statistical methods are used to infer the likely value of the parameter on the basis of a statistic computed from a sample taken from the population. For example, the sample mean is an unbiased estimator of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Play
In baseball and softball, a double play (denoted as DP in baseball statistics) is the act of making two outs during the same continuous play. Double plays can occur any time there is at least one baserunner and fewer than two outs. In Major League Baseball (MLB), the double play is defined in the Official Rules in the Definitions of Terms, and for the official scorer in Rule 9.11. During the 2016 Major League Baseball season, teams completed an average 145 double plays per 162 games played during the regular season. Examples The simplest scenario for a double play is a runner on first base with less than two outs. In that context, five example double plays are: * The batter hits a ground ball ** to an infielder or the pitcher, who throws the ball to one of the middle infielders, who steps on second base to force out the runner coming from first (first out), and then throws the ball to the first baseman in time to force out the batter (second out). As both outs are made by force ... [...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 earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Games Played
Games played (GP) is a statistic used in team sports to indicate the total number of games in which a player has participated (in any capacity); the statistic is generally applied irrespective of whatever portion of the game is contested. Baseball In baseball, the statistic applies to players, who prior to a game, are included on a starting lineup card or are announced as an ''ex ante'' substitute, whether or not they play. For pitchers only, the statistic games pitched is used. A notable example of the application of the above rule is pitcher Larry Yount, who suffered an injury while throwing warmup pitches after being summoned as a reliever in a Major League Baseball (MLB) game on September 15, 1971. He did not face a batter, but was credited with an appearance because he had been announced as a substitute. Yount never appeared in (or actually played in) any other MLB game. Association football In association football, a game played is counted if a player is in the Starting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assist (baseball)
In baseball, an assist (denoted by A) is a defensive statistic, baseball being one of the few sports in which the ''defensive'' team controls the ball. An assist is credited to every defensive player who fields or touches the ball (after it has been hit by the batter) prior to the recording of a putout, even if the contact was unintentional. For example, if a ball strikes a player's leg and bounces off him to another fielder, who tags the baserunner, the first player is credited with an assist. A fielder can receive a maximum of one assist per out recorded. An assist is also credited if a putout would have occurred, had another fielder not committed an error. For example, a shortstop might field a ground ball cleanly, but the first baseman might drop his throw. In this case, an error would be charged to the first baseman, and the shortstop would be credited with an assist. If a pitcher records a strikeout where the third strike is caught by the catcher, the pitcher is not credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Putout
In baseball statistics, a putout (denoted by ''PO'' or ''fly out'' when appropriate) is awarded to a defensive player who (generally while in secure possession of the ball) records an out by one of the following methods: * Tagging a runner with the ball when he is not touching a base (a tagout) * Catching a batted or thrown ball and tagging a base to put out a batter or runner (a force out, or if done after a flyout, a doubling off) * Catching a thrown ball and tagging a base to record an out on an appeal play * Catching a third strike (a strikeout) * Catching a batted ball on the fly (a flyout) * Being positioned closest to a runner called out for interference In a regulation nine-inning game, the winning team will always have a total of 27 putouts, as one putout is awarded for every defensive out made; this is one aspect of proving a box score.

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 Players can ...

Shortstop
Shortstop, abbreviated SS, is the baseball or softball fielding position between second and third base, which is considered to be among the most demanding defensive positions. Historically the position was assigned to defensive specialists who were typically poor at batting and were often placed at the bottom of the batting order. Today, shortstops are often able to hit well and many are placed at the top of the lineup. In the numbering system used by scorers to record defensive plays, the shortstop is assigned the number 6. More hit balls go to the shortstop than to any other position, as there are more right-handed hitters in baseball than left-handed hitters, and most hitters have a tendency to pull the ball slightly. Like a second baseman, a shortstop must be agile, for example when performing a 4-6-3 double play. Also, like a third baseman, the shortstop fields balls hit to the left side of the infield, where a strong arm is needed to throw out a batter-runner befo ...

Third Baseman
A third baseman, abbreviated 3B, is the player in baseball or softball whose responsibility is to defend the area nearest to third base — the third of four bases a baserunner must touch in succession to score a run. In the scoring system used to record defensive plays, the third baseman is assigned the number 5. Third base is known as the "hot corner", because the third baseman is often the infielder who stands closest to the batter—roughly 90–120 feet away, but even closer if a bunt is expected. Most right-handed hitters tend to hit the ball hard in this direction. A third baseman must possess good hand-eye coordination and quick reactions to catch batted balls whose speed can exceed . The third base position requires a strong and accurate arm, as the third baseman often makes long throws to first base or quick ones to second base to start a double play. As with middle infielders, right-handed throwing players are standard at the position because they do not need to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Baseman
A first baseman, abbreviated 1B, is the player on a baseball or softball team who fields the area nearest first base, the first of four bases a baserunner must touch in succession to score a run. The first baseman is responsible for the majority of plays made at that base. In the numbering system used to record defensive plays, the first baseman is assigned the number 3. Also called first sacker or cornerman, the first baseman is ideally a tall player who throws left-handed and possesses good flexibility and quick reflexes. Flexibility is needed because the first baseman receives throws from the other infielders, the catcher and the pitcher after they have fielded ground balls. In order for the runner to be called out, the first baseman must be able to ''stretch'' towards the throw and catch it before the runner reaches first base. First base is often referred to as "the other hot corner"—the "hot corner" being third baseman, third base—and therefore, like the third baseman ...

Catcher
Catcher is a Baseball positions, position in baseball and softball. When a Batter (baseball), batter takes their at bat, turn to hit, the catcher crouches behind home plate, in front of the (home plate, home) Umpire (baseball), 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 Batting (baseball), 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 ...
