Before drafting J.T. Ginn in the first round of the 2018 draft, the Dodgers hadn’t selected a prep arm since Grant Holmes in 2014. With the college bat class lacking a bit, the Dodgers might be more inclined to look to the prep ranks. Petty is one of the best high school arms available. He threw an 18-strikeout no-hitter at the end of April and, despite not having prototypical size, has massive upside.

Petty works with a fastball that sits in the mid-to-high-90s and has cracked triple digits on a few occasions. It also features some significant movement and sink — not dissimilar to Bachman. He pairs it with an absolute wipeout slider in the high-80s. He also has a high-80s changeup that has improved, but still needs some work. He’ll need all three of his pitches if he’s to remain a starter as his career progresses. He also has great makeup and an advanced feel for pitching for a kid his age.

There’s some effort in his delivery. Scouts are split on whether he can remain in the rotation, but the higher effort definitely gives him some reliver risk. His release point is three-quarters, which helps him get some run on his fastball. He has a little arm whip, but his quick arm and strong lower-half helps him generate elite-level velocity. His command wavers a bit because of the higher effort delivery, but the Dodgers are good at getting their pitching prospects to iron things out, especially since he has an athletic frame. Physically, he reminds me a bit of Walker Buehler, and we see what the Dodgers have done with him since taking him in the first round of the 2015 draft.


Prep arms — especially right-handers — tend to fall a bit on draft day. There’s more risk in a prospect like Petty vs. a more polished college pitcher. He has a commitment to the University of Florida, and if the Dodgers took him at 29, they’d have to use at least their entire slot amount to get him out of that (and maybe even a little more). But the talent is undeniable. He has No. 2 starter upside, but also significant risk.
