Alcantara’s changeup is used, as its name suggests, to change up speeds from his sinker. He throws his sinker and changeup in similar locations to make the speed more deceptive.
His sinker is his primary pitch, which he throws inside to right-handed hitters. When he keeps it down in the zone, it can be filthy, but when he leaves it up, there is rarely a swing-and-miss on it.
Alcantara throws his slider even less often, and it is not developed at all. It is easily one of the worst sliders in the league, but if he could turn it into an average pitch, he could be one of the better relievers in the Tigers’ pen.
Alcantara’s sinker was one of the more unheralded nasty pitches in 2018. He generated an excellent 40.0% O-swing rate and a 1.0 pVal thanks to a wicked amount of arm-side run. However, Alcantara will need to generate more swings and misses (7.4% swinging-strike rate) in order to stick in the bullpen long-term.
Alcantara’s top secondary is his changeup, and like his sinker, this pitch is hard with heavy arm-side run. He posted a great 41.7% O-swing rate and a 15.9% swinging-strike rate, leading to a 1.7 pVal. This pitch is the key to Alcantara’s future big league success.
Alcantara’s slider averaged a tidy 90 mph last season, with a limited amount of movement and a low 30.8% zone rate. While he did generate a 23.1% swinging-strike rate, this pitch will need to find more of the zone to be effective going forward.
