if that's true ("much higher"), it doesn't seem to bear out in any meaningful way in the stats. Ohtani had a 0.016 higher average, lower OBP, lower SLG
Ohtani's K rate in the MLB has increased vs NPB (obviously to be expected)
He strikes out every 3.38 ABs vs every 3.19 ABs in the NPB
Ohtani is below league average in Zone Contact (MLB: 82.5%, Ohtani: 75.9%)
