Feliz’s changeup had nine ticks of separation from his fastball, which is good separation. The pitch got just a 7.7% SwStr% and 16.7% O-Swing% and didn’t strike out a single batter.
Feliz’s fastball was almost a complete repeat from his 2018 season. The only difference was swapping some doubles for homers along with having a small tick up in SwStr% and K%.
Feliz’s slider was his money-maker as it combined a 27% SwStr% and 40.7% O-Swing% to hit a career-high 51.6% K%. He also tied a career-best 14.3% LD%.
Feliz’s fastball velocity dropped a few mph in 2018 and generated more contact. Despite this, he actually improved his results perhaps trusting in his defense more, as his BABIP dropped significantly with an increase in ground-ball percentage.
Feliz’s slider is his main breaking pitch. However, he threw it less in 2018 than in previous years as it is generating less whiffs and more contact.
Another of Feliz’s seldomly thrown pitches, his two-seamer/sinker was usually put into play. That is a significant reason to keep that pitch in your pocket.
Feliz did not throw many changeups as he couldn’t keep it in the zone. When he did there was a good chance it lead to a hit.
