A statistic that measures a player's batting ability by comparing the number of hits he has to his number of at bats. A player's batting average is used to evaluate his individual skill at batting. Batting Average does not include walks or hit by pitches. It also does not specify the difference between a single, double, triple, or home run - each are considered to be a single hit.
Batting average is calculated as follows: hits divided by at bats. For example, during the 2011 MLB season Jose Bautista had 155 hits over 513 at bats for a .302 batting average.
The league-wide batting average has generally ranged between .250 and .275, and players with batting averages above .300 are considered to be very good batters. A batting average of .400 over a season is considered to be the ultimate achievement by a batter and is nearly unattainable in modern baseball. Ted Williams was the last player to achieve this feat, way back in 1941.
The player in each league (National League and American League) with the highest batting average, who meets the at bats requirement of needing at least 3.1 at bats per scheduled team game, is awarded the league batting title by the MLB.
Ty Cobb holds the record for the most batting titles with 11.
