Chris Davis or Mickey Mantle?
Mickey Mantle’s highest single season slugging pct was .705 back in 1956. Baltimore Orioles first baseman Chris Davis is slugging .720 through 72 games this season.
We are isolating just 303 plate appearances so expect Davis to regress quite a bit in the second half of the year, but if he kept this pace up it would be historic. Besides one-off seasons by Mark McGwire and Frank Thomas, Davis’ .720 slugging would be the highest in the American League since Ted Williams in 1957 (.731 SLG).
