Getting back to Ohtani, as visually impressive as he is, the results are ok. Below are his career numbers, which to this point are a grand total of 58 innings pitched. Not bad but not to the level of hype:
4.19 ERA
3.88 FIP
3.87 XFIP
5.43 BB/9
The ERA and advanced stats aren't bad, especially today, but until he gets his walk numbers down, he'll never reach his potential as a pitcher.
