The curveball (marked as a slider on Statcast) was responsible for all six of Vizcaino’s 2019 strikeouts. Despite the small sample (just 32 thrown), the pitch did not give up a hit, and of the 14 swings hitters took, seven were whiffs. The curve averages 12.6 mph slower than his fastball and has had a positive pVAL in each of the last five years.
Vizcaino’s average fastball velocity was down 1.5 mph from its usual marks from 2015 through 2018. Either the shoulder injury that forced a season-ending surgery brought his fastball velo down to 96 mph, or he just wasn’t able to build enough strength in his four MLB innings. His 36 fastballs thrown were tagged to the tune of a .750 BAA and a 2.000 SLG against.
Averaging 97.6 mph in 2018, the fastball was a quality pitch for Vizcaino in 2018. It featured a 10.3% swinging-strike rate despite a 57.4% zone rate and allowed a .258/.349/.430 slash line. The result was a 0.4 pVal.
Thrown about 30.63% of the time, Vizcaino’s slider was his best pitch by far according to pVal with a 4.6 mark. Opponents managed just a 43.2% contact rate against the pitch while also failing to hit a home run against it. The result was a weak .128/.163/.213 slash line against the pitch.
Despite throwing just 22 of them in 2018, Vizcaino’s changeup was pretty effective pVal-wise with a 0.2 mark. A 10.5% swinging-strike rate along with a 100% ground-ball rate led to a .000 batting average against.
