Introduction

Baseball Statistics numerical information about the performance of baseball players and teams. Some statistics, such as the number of hits or errors a player makes in a season, are simply counted. Others, such as batting average and fielding percentage, are calculated using mathematical formulas. Statistics record and preserve baseball’s history, creating a repository of information that deepens understanding and appreciation of the sport. This information is used by everyone from players and managers to club executives and player agents to fans and fantasy baseball league participants. As statistics become more numerous and complex, computers are increasingly utilized to compile and analyze them.

Baseball statistics focus on the offensive, defensive, and pitching performances of players, making it possible to compare the contributions of players on different teams and to assess their part in the team’s success or failure. Statistics also make it possible to compare the strengths and weaknesses of players and teams of different periods. Most offensive statistics concern a player’s actions while batting or on base. These include getting on base, driving in runs, striking out, executing sacrifices, stealing bases, and scoring runs. Defensive statistics record players’ fielding activities, such as handling a hit ball without error, throwing out base runners, and making putouts. Pitchers and catchers have their own special set of statistics. Pitchers’ statistics include win-loss record, strikeouts, walks allowed, earned run average (ERA), innings pitched, and wild pitches. Catchers’ statistics include runners caught stealing, passed balls, and catcher’s interference.
