List of Major League Baseball career batting average leaders
In baseball, the batting average (BA) is defined by the number of hits divided by at bats. It is usually reported to three decimal places and pronounced as if it were multiplied by 1,000: a player with a batting average of .300 is "batting three hundred." A point (or percentage point) is understood to be .001.
