Limited to only 32 change-ups because of injury, Borucki had troubles with his best pitch in 2019. He gave up a .524 wOBA on the pitch and a lot of hard-contact (90.9 average EV).
Borucki’s sinker was destroyed in 2019, giving up a 1.407 OPS and an average EV of 96.6. Coming into 2020 fully healthy, hopefully he can return to his 2019 form of 1.3 pVAL.
His best pitch in terms of results in 2019 (.464 wOBA against wooo), Borucki used his slider as his primary secondary. With just 42 thrown, it accumulated -1.5 pVAL showcasing just how bad it was.
Borucki hardly gets any swings and misses with the four-seamer, but it’s around the zone. When Borucki throws the pitch for strikes it almost always gets put in play, and batters were decent against it.
The changeup is Borucki’s No. 2 pitch, just ahead of his slider. It performed well in 2018, getting strikes and allowing just a .222 average.
Borucki’s slider is basically two different pitches, as its velocity ranges from low 70s to mid 80s. It had a solid strikeout rate and generated weak contact.
