Season-high OBP For Right-Handed Hitters
Only 4 right-handed hitters have ever recorded an on-base percentage of .500+ for a single season. Rogers Hornsby, the greatest right-handed hitter in history, achieved a .507 OBP in 1924. Joe Kelley chalked up a .502 OBP figure in 1894, as did the remarkable Hugh Duffy in 1894. Ed Delahanty, one of only 3 hitters to ever bat over .400 in a season 3 times, registered a .500 OBP in 1895.
By the way, the other 2 hitters with three .400+ seasons are Rogers Hornsby and the incomparable Ty Cobb.
