In 1919, Babe Ruth slashed .322/.456/.657 with 29 home runs. He also started 12 games as a pitcher, posting a 2.97 ERA with 2 strikeouts per 9 innings.
In 2021, at the halfway mark of the season, Shohei Ohtani is slashing .280/.364/.705 with 30 home runs. He has also started 12 games as a pitcher, posting an ERA of 3.60 with 12.45 strikeouts per 9 innings.
Shohei Ohtani will never come close to Babe Ruth's OPS (Ruth routinely hit just short of .400 once he became a pure hitter) but also keep in mind that Babe Ruth really only tried be both a pitcher and an everyday hitter for 2 years, 1918-1919.
I feel comfortable saying that Shohei Ohtani is probably the most unique MLB player I have seen in my lifetime. I would go so far as to predict that if I live another 30-40 years, I am more likely to see another Willie Mays than another Shohei Ohtani.
