If you want to flush a prospect after <100 major league PA at age 23, I don't know what to say. 41 OPS+ isn't what Rortvedt "is".
Elsewhere, a comp was made to Drew Butera. Rortvedt lost his age-22 season to Covid, but at age 21 he OPSed .687 at AA, while at the same age Butera managed .603 at low-A. At 23, Rortvedt did .750 at AAA, and Butera did .765 at high-A. Being 2 league levels higher at the same age, that is huge when comparing.
Rortvedt's has been developing as a hitter, just fine. He won't win any batting titles, because catchers not named Mauer generally don't. But he's going to hit. Especially now that he's been traded, because, Twins, y'know. And people are going to be, all, "well, that came out of nowhere."
