List of Major League Baseball players with a .400 batting average in a season

In baseball, batting average (AVG) is a measure of a batter's success rate in achieving a hit during an at bat, and is calculated by dividing a player's hits by his at bats. The achievement of a .400 batting average in a season was historically recognized as the coveted "standard of hitting excellence", in light of how batting .300 in a season is already regarded as very good.
