Wittgren allowed the highest average exit velocity in baseball last season. His changeup was his hardest-hit offering, averaging 93.9 mph while generating a 7.76 FIP; the pitch was wildly ineffective.
Without elite velocity (92.3 mph), run, or rising action, Wittgren’s fastball was still his most effective pitch by nearly every metric. Its K-BB% of 22.9% was above average and generated a surprising amount of whiffs (23.2%). Although, the pitch was responsible for 70% of Wittgren’s HRs allowed.
Used almost exclusively against righties, Wittgren’s slider produced his highest whiff percentage at 30.9% while issuing 0 walks in 2019. Otherwise, the pitch was extraordinarily boring, striking out only 13.6% of hitters and allowing a 47.4 hard-hit rate.
Wittgren throws the four-seamer way more than any other pitch, and it was easily his best offering in 2018. The four-seamer had an 8.7 pitch value and allowed a measly .122 average.
Wittgren throws the change slightly more than the curveball, and it’s typically been more effective. It was around the zone and hitters didn’t do much against the pitch in 2018.
This bender is slightly behind Wittgren’s changeup, coming in as his No. 3 pitch. It was hammered in 2018, giving up a .500 average over a somewhat significant sample.
The sinker was well behind Wittgren’s three other pitches in usage. It was mediocre in 2018 in limited action, giving up a few too many line drives to be effective.
