Here is a list of all-time greats, plus one player who presumably doesn’t belong with this group. Except that he does belong.
These are the only players since 1901 to accomplish what feat.
Hint: the feat is in multiple parts.
I have managed to stump our esteemed panel here (a pretty rare feat). The answer is that the above players are the only ones with a season since 1901 of 120 runs, .600 slugging, and HRs of less than one-third of extra-base hits.
