18. .406 Batting Average in a Single Season
Team/Player: Ted Williams
Considered sacred by many, Ted Williams' .406 batting average in 1941 is the last time a Major League hitter has hit above .400 in a season. It is no coincidence that this mark hasn't been reached since baseball's 1947 racial integration, which introduced to the game a bevy of capable pitchers who were both African-American as well as Latino. The vast increase in the talent pool means that some of those cheap hits Williams was able to record off of inferior opponents are no longer a realistic option, and instead become outs.
