Quinn Priester was sent down to the minors yesterday, after making six starts with the Pittsburgh Pirates. Priester had a 9.10 ERA in 28.2 innings of work.
Priester has one of the best curveballs in the system. That resulted in a .733 OPS and a 12.9% whiff rate in the big leagues. The downside to the pitch isn’t the actual pitch. It’s what Priester pairs with the curveball. His four-seam fastball has been crushed to the tune of a 1.397 OPS, with a 5.9% whiff rate. That pitch sets up the high/low split on the curve, and Priester is missing with the setup.
