Baseball Abbreviations

Tony Gwynn had another typically great season in 1997: 592 AB, 220 H, and his AVG was a National League leading .372. What do all those abbreviations stand for? Baseball Almanac is pleased to present a common set of abbreviations seen and used in print on a regular basis.

During the 1960s a Special Baseball Records Committee was formed by Major League Baseball to evaluate the erratic records kept prior to the 1920 season.
