No, it's not. His average exit velo is like 97mph. This was bound to even out.
So, he doesn't strike out, doesn't really chase, is very selective and smokes the ball when he makes contact. There's no way he was ever going to remain a below average hitter.
Yeah, he's probably not an over 200 wRC+ hitter, but settling into the 130-140 range is pretty easy to see given what he's done so far.
Fun fact, after that game, he has a higher WAR than Danny Jansen. He should be the starter. He's worked extremely well with pitchers who have tons of movement and velocity but little idea of where it's going, while also doing a pretty great job framing. His game calling does not appear to be an issue.
This guy came from A+ to the majors and looks like he belongs. That's remarkable. If he can drop 30-40 pounds, we have a long term superstar on our hands.
