As someone raised on ‘90s American League baseball, I was always going to be predisposed to preferring the designated hitter over pitchers hitting. That being said, while I disagreed with the reasoning, I understand why an NL person might prefer the opposite. One point that absolutely should not be in doubt though is the entertainment factor of a DH versus a pitcher.
Pitchers have typically never been great hitters, but by 2021, the final year before the universal DH, things got ugly. Of pitchers with at least 50 plate appearances, only Max Fried and Germán Márquez put up an OPS+ over 30.
