Most Extra Base Hits In A Season
Babe Ruth holds the record for most extra base hits in a season with 119, in 1921. The 2nd best such total is 117 by the Hall of Famer Lou Gehrig, in 1927.
Only Lou Gehrig, Chuck Klein and Todd Helton have ever recorded 2 seasons of at least 100+ extra base hits… a rare feat. Lance Berkman, then of the Houston Astros, set the record for most extra base hits by a switch-hitter with 94, in 2001.
