Baseball statistics include a variety of metrics used to evaluate player and team performance in the sport of baseball.
In baseball, an at bat (AB) or time at bat is a batter's turn batting against a pitcher. An at bat is different from a plate appearance. A batter is credited with a plate appearance regardless of what happens during their turn at bat, but a batter is charged with an at bat only if that plate appearance does not have one of the results enumerated below. While at bats are used to calculate certain statistics, including batting average and slugging percentage, a player can qualify for the season-ending rankings in these categories only if they accumulate 502 plate appearances during the season.
A base on balls (BB), better known as a walk, occurs in baseball when a batter receives four pitches during a plate appearance 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). Despite being known as a "walk", it is considered a faux pas for a professional player to actually walk to first base; the batter-runner and any advancing runners normally jog on such a play.
In baseball statistics, on-base percentage (OBP) measures how frequently a batter reaches base. An official Major League Baseball (MLB) statistic since 1984, it is sometimes referred to as on-base average (OBA), as it is rarely presented as a true percentage.
On-base plus slugging (OPS) is a sabermetric baseball statistic calculated as the sum of a player's on-base percentage and slugging percentage. The ability of a player both to get on base and to hit for power, two important offensive skills, are represented. An OPS of .800 or higher in Major League Baseball puts the player in the upper echelon of hitters. Typically, the league leader in OPS will score near, and sometimes above, the 1.000 mark.
In baseball, a player is credited with a plate appearance 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 ; 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. A very similar baseball statistic, at bats, counts a subset of plate appearances that end under certain circumstances.
Walter Perry Johnson, nicknamed "Barney" and "the Big Train", was an American professional baseball player and manager. He played his entire 21-year baseball career in Major League Baseball as a right-handed pitcher for the Washington Senators from 1907 to 1927. He later served as manager of the Senators from 1929 through 1932 and of the Cleveland Indians from 1933 through 1935.
In baseball or softball, a strikeout occurs when a batter accumulates three strikes during a time at bat. It means the batter is out, unless the third strike is not caught by the catcher and the batter reaches first base safely as a result. A strikeout is a statistic recorded for both pitchers and batters, and is usually denoted by the letter K, or sometimes by the initialism SO. A "strikeout looking"—in which the batter does not swing and the third strike is called by the umpire—may be denoted by an inverted K.
William Henry Keeler, nicknamed "Wee Willie" because of his small stature, was an American right fielder in Major League Baseball who played from 1892 to 1910, primarily for the Baltimore Orioles and Brooklyn Superbas in the National League, and the New York Highlanders in the American League. Keeler, one of the best hitters of his time, was elected to the National Baseball Hall of Fame in 1939. One of the greatest contact hitters of all time and notoriously hard to strike out, Keeler has the highest career at bats-per-strikeout ratio in MLB history, averaging 63.17 at bats between each strikeout. His plate appearance-per-strikeout ratio is also one of the best of all time, with Keeler averaging 70.66 plate appearances between strikeouts, second only to Joe Sewell, another Hall of Famer, who averaged 73.06 plate appearances between each strikeout.
José Dennis Martínez Ortiz, nicknamed "El Presidente", is a Nicaraguan former professional baseball pitcher. Martínez played in Major League Baseball (MLB) for the Baltimore Orioles, Montreal Expos, Cleveland Indians, Seattle Mariners, and Atlanta Braves from 1976 to 1998. He threw a perfect game in 1991, and was a four-time MLB All-Star. He was the first Nicaraguan to play in the majors.
In baseball, fielding independent pitching (FIP) is intended to measure a pitcher's effectiveness based only on statistics that do not involve fielders. These include home runs allowed, strikeouts, hit batters, walks, and, more recently, fly ball percentage, ground ball percentage, and line drive percentage. By focusing on these statistics and ignoring what happens once a ball is put in play, which – on most plays – the pitcher has little control over, DIPS claims to offer a clearer picture of the pitcher's true ability.
Justin Brooks Verlander is an American professional baseball pitcher for the Houston Astros of Major League Baseball (MLB). He has previously played in MLB for the Detroit Tigers and New York Mets. A three-time Cy Young Award winner as well as an AL MVP recipient, Verlander is considered one of the greatest pitchers in baseball history.
In baseball statistics, strikeouts per nine innings pitched is the mean of strikeouts by a pitcher per nine innings pitched. It is determined by multiplying the number of strikeouts by nine, and dividing by the number of innings pitched.
The 1963 Los Angeles Dodgers were led by pitcher Sandy Koufax, who won both the Cy Young Award and the Most Valuable Player Award. The team went 99–63 to win the National League title by six games over the runner-up St. Louis Cardinals and beat the New York Yankees in four games to win the World Series, marking the first time that the Yankees were ever swept in the postseason.
1903 was the third year for the Detroit Tigers in the still-new American League. The team finished in fifth place with a record or 65–71 (.478), 25 games behind the Boston Americans. The 1903 Tigers outscored their opponents 567 to 539. The team's attendance at Bennett Park was 224,523, sixth out of the eight teams in the AL.
The 1977 Detroit Tigers finished in fourth place in the American League East with a record of 74–88, 26 games behind the New York Yankees. They were outscored by their opponents 751 to 714. The Tigers drew 1,359,856 fans to Tiger Stadium in 1977, ranking 7th of the 14 teams in the American League.
The 1983 Detroit Tigers finished in second place in the American League East with a record of 92–70 (.568), six games behind the Orioles. The Tigers outscored their opponents 789 to 679. The Tigers drew 1,829,636 fans to Tiger Stadium in 1983, ranking 8th of the 14 teams in the American League.
The Tigers entered the season as the reigning World Series champions. The 1985 Detroit Tigers finished in third place in the American League East with a record of 84–77 (.522), 15 games behind the Blue Jays. The Tigers outscored their opponents 729 to 688. The Tigers drew 2,286,609 fans to Tiger Stadium in 1983, ranking 3rd of the 14 teams in the American League.
In baseball, batting average (BA) is determined by dividing a player's hits by their total at-bats. It is usually rounded to three decimal places and read without the decimal: A player with a batting average of .300 is "batting three hundred". If necessary to break ties, batting averages could be taken beyond the .001 measurement. In this context, .001 is considered a "point", such that a .235 batter is five points higher than a .230 batter.
