Opponent Batting Average
In baseball statistics, batting average against (denoted by BAA or AVG), also known as opponents' batting average (denoted by OBA), is a statistic that measures a pitcher's ability to prevent hits during official at bats. It can alternatively be described as the league's hitters' combined batting average against the pitcher. Definition Batting average against is calculated as: BAA = \frac for which: *H is the number of hits allowed by the pitcher *BF is the number of batters faced *BB is the number of base on balls *HBP is the number of hit batsmen *SH is the number of sacrifice hits *SF is the number of sacrifice flies *CINT is the number of catcher's interference For example, if a pitcher faced 125 batters and allowed 25 hits, issued 8 walks, hit 1 batsman, allowed 2 sacrifice hits, allowed 3 sacrifice flies, and had 1 instance of catcher's interference, the pitcher's BAA would be calculated as: BAA = \frac = \frac = .227 Reference site Baseball-Reference.com more simpl ...

Sandy Koufax
Sanford Koufax (; born Sanford Braun; December 30, 1935) is an American former left-handed pitcher in Major League Baseball (MLB) who played his entire career for the Brooklyn/Los Angeles Dodgers from 1955 to 1966. He has been hailed as one of the greatest pitchers in baseball history. After joining the major leagues at age 19, having never pitched a game in the minor leagues, the first half of his career was unremarkable, posting a record of just 36–40 with a 4.10 earned run average (ERA); he was a member of World Series champions in both Brooklyn and Los Angeles, though he did not appear in any of the team's Series wins. But after making adjustments prior to the 1961 season, and benefitting from the team's move into expansive Dodger Stadium a year later, Koufax quickly rose to become the most dominant pitcher in the major leagues before arthritis in his left elbow ended his playing days prematurely at age 30. Koufax was an All-Star in each of his last six seasons, lead ...

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 ...

Hits Per Nine Innings
In baseball statistics, hits per nine innings (denoted by H/9) is the average number of hits allowed by a pitcher in a nine inning period; calculated as: (hits allowed x 9) / innings pitched. This is a measure of a pitcher's success based on the number of all outs he records. Compared to a pitcher's batting average against, a pitcher's H/9 benefits from sacrifice bunts, double plays, runners caught stealing, and outfield assist, but it is hurt by some errors. Unlike batting average against, a pitcher's H/9 benefits from outs that are not related to official at bats, as they are recorded on runners after they have reached base. , Nolan Ryan is the career leader (6.5553), Sandy Koufax is #2 (6.7916), Clayton Kershaw is #3 (6.8160). See also *Walks plus hits per inning pitched In baseball statistics, walks plus hits per inning pitched (WHIP) is a sabermetric measurement of the number of baserunners a pitcher has allowed per inning pitched. WHIP is calculated by adding the n ...

Major League Baseball
Major League Baseball (MLB) is a professional baseball organization and the oldest major professional sports league in the world. MLB is composed of 30 total teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. The NL and AL were formed in 1876 and 1901, respectively. Beginning in 1903, the two leagues signed the National Agreement and cooperated but remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan. It is also included as one of the major professional sports leagues in the United States and Canada. Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869. Before that, some teams had secretly paid certain players. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one t ...

Catcher's Interference
In baseball, interference occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules. Offensive interference The most common incidence of interference occurs when a member of the offensive team physically hinders the defensive team, decreasing its chances to make an out or increasing the chance that a baserunner will advance. Whenever this ''offensive interference'' occurs, the ball becomes dead. If the interference was committed by a batter or a baserunner, that player is called out and all other runners must return to the bases they occupied at the time of the interference. If interference is committed by a runner with the obvious intent of preventing a double play, the batter-runner will be called out in addition to the runner who committed t ...

Sacrifice Fly
In baseball, a sacrifice fly (sometimes abbreviated to sac fly) is defined by Rule 9.08(d): "Score a sacrifice fly when, before two are out, the batter hits a ball in flight handled by an outfielder or an infielder running in the outfield in fair or foul territory that # is caught, and a run scores after the catch, or # is dropped, and a runner scores, if in the scorer's judgment the runner could have scored after the catch had the fly ball been caught." It is called a "sacrifice" fly because the batter allows a teammate to score a run, while sacrificing his own ability to do so. Sacrifice flies are traditionally recorded in box scores with the designation "SF". Rules As addressed within Rule 9.02(a)(1) of the Official Baseball Rules a sacrifice fly is not counted as a time at bat for the batter, though the batter is credited with a run batted in. The same is true with a bases-loaded walk. The purpose of not counting a sacrifice fly as an at-bat is to avoid penalizing hitte ...

Sacrifice Hit
In baseball, a sacrifice bunt (also called a sacrifice hit) is a batter's act of deliberately bunting the ball, before there are two outs, in a manner that allows a baserunner to advance to another base. The batter is almost always put out, and hence sacrificed (to a certain degree that is the intent of the batter), but sometimes reaches base on an error or fielder's choice. In that situation, if runners still advance bases, it is still scored a sacrifice bunt instead of the error or the fielder's choice. Sometimes the batter may safely reach base by simply outrunning the throw to first; this is not scored as a sacrifice bunt but rather a single. A successful sacrifice bunt does not count as an at bat, does not impact a player's batting average, and counts as a plate appearance. Unlike a sacrifice fly, a sacrifice bunt is not included in the calculation of the player's on-base percentage. If the official scorer believes that the batter was attempting to bunt for a base hit ...

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 important ...

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 ...

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 Seatt ...
