The concept of batting average has a long history in the sport of baseball. It was first introduced in the mid-19th century and has been a fundamental statistic in the sport ever since. Over the years, batting average has been used to evaluate the performance of some of the greatest players in baseball history, from Ty Cobb, who holds the record for the highest career batting average, to Ted Williams, the last player to hit over .400 in a season.
