context_page_description: In baseball, batting average 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 is recognized as "the standard of hitting excellence", in light of how batting .300 in a season is already regarded as solid. Twenty players have recorded a batting average of at least .400 in a single Major League Baseball season as of 2018, the last being Ted Williams of the Boston Red Sox in 1941. Three players – Ed Delahanty, Ty Cobb and Rogers Hornsby – have accomplished the feat in three different seasons, and no player has ever hit over .440, a single-season record established by Hugh Duffy in 1894. Ross Barnes was the first player to bat .400 in a season, posting a .429 batting average in the National League's inaugural 1876 season.
  In total, 20 players have reached the .400 mark in MLB history and five have done so more than once. Of these, ten were right-handed batters, nine were left-handed, and one was a switch hitter, meaning he could bat from either side of the plate. Two of these players played for only one major league team.
