Amazingly, there was one guy who pitched enough to qualify for the ERA title while managing to drive in more runs than he allowed — some old guy named George Herman Ruth. He pitched 166 1/3 innings in 1918, while allowing 51 runs — 41 of them earned. Both numbers are below the 61 he drove in, while appearing in 75 more games in total than he pitched in. Ohtani has certainly shown the capacity to join the club.
