Alex Wilson’s fastball had an average velocity of 91.6 mph and allowed a .333 BAA. The pitch was offered at 47.3% of the time, and of the 93 he threw on the seaon, Wilson had just five swings-and-misses. Of the six strikeouts he earned with the pitch, four were called and two were high out-of-the-zone whiffs by Paul Goldschmidt and Yasiel Puig. Perhaps the fastball would see more success if he located high in the zone more often.
Statcast marks this as a slider, but Fangraphs has it as a cut fastball. Regardless, it is Wilson’s most used pitch at just under 54% in 2019. The usage was similar to 2018, but it is hard to get a gauge on his repertoire in his just 11.1 innings pitched on the season. Before being DFA’d on April 29, Wilson’s average velocity on the slider was 85.7 mph and had a 47.2 swing% and a 29.4 whiff%, generating seven strikeouts but surrendering two home runs and a .296 BAA.
Wilson’s slider wasn’t a great pitch peripheral-wise. It failed to miss many bats with just a 5% swinging-strike rate, and opposing hitters slugged .600 against it. Overall it was worth a -0.2 pVal
Wilson’s two-seam fastball averaged the same velocity as his four-seam fastball but featured significantly more depth in terms of movement, which contributed to 50% ground-ball rate. Opposing hitters put it in play plenty though, highlighted by a 93% contact rate, which when coupled with a .341 BABIP against led to a .327 batting average against.
Averaging 92.2 mph in 2018, Wilson’s four-seam fastball baffled hitters to the tune of a .176 batting average against thanks to a .174 BABIP on the pitch. What makes it more impressive is that he threw it in the zone 52.9% of the time while giving up just a 79.1% contact rate with the pitch. It may be the third-most used pitch for Wilson, but it was his second-best option with a 1.9 pVal.
Wilson rarely features this changeup, which had just a 1.7% usage rate in 2018. Despite generating a 100% ground-ball rate and .000 batting average against, it’s best to consider this the clear fifth option for Wilson.
