Middleton’s changeup is kept on the inside part of the zone against righties.
In 2019 Middleton’s fastball got crushed because it seems like he kept it in the zone. He doesn’t throw incredibly hard, so it makes sense that it got crushed.
His slider moves away from righties and he seemed to throw it into the dirt a good amount. His misses are generally in the zone and hitters did a good job of hitting those pitches hard.
