Estevez threw his changeup just 4% of the time, but hit the zone 52.3% of the time and got a 30% K rate on the pitch
Estevez’s fastball hit the zone 58.9% of the time and allowed a 42.2% FB rate. Unfortunately, in the year of the juiced ball, the pitch also allowed a 20.4% HR/FB rate, which led to a .262 ISO.
Estevez’s slider found the zone 48.1% of the time and posted a 12.8% SwStr%. The pitch performed well, allowing just a 43 wRC+.
Estevez averaged a blistering 97 mph on his fastball last season. He generated an 11.5% swinging strike rate and a 21.5% strikeout rate, both improvements from his 2016 debut. His 2.5 pVAL was an improvement as well. At 25, there is a bright future for Estevez if he keeps improving.
Estevez’s slider saw a significant decrease in swinging-strike rate, and a nearly 20% increase in contact made. He needs to get this pitch away from the strike zone if he wants to find any success and improve upon his ugly -1.3 pVAL from 2017.
Batters made way too much contact with Estevez’s changeup in 2017, hitting .429 off the pitch thanks to a 81.8% contact rate. Already not a pitch he used much, Estevez could consider abandoning the pitch altogether and sticking with a two-pitch arsenal going forward.
