Alexander threw this pitch 9 times and produced two strikeouts on it. Even in 2018 he only threw it 39 times and it was quite effective when he threw it.
His usage% on this pitch in 2019 was 88.8%, and it is a good one to throw 88.8% of the time. He throws it low and in against lefties and profiles like Zack Britton.
Another pitch he doesn’t use often, Alexander uses it to catch hitters who are expecting a low in and sinker off guard.
Alexander almost exclusively utilizes his sinker. While he was able to increase his arm-side run on the sinker, he generated fewer swings outside the zone as well as fewer swings and misses overall. The extreme ground ball tendencies of the sinker limit the damage against it and it continues to be effective.
After nearly eliminating the it in 2017, Alexander featured the slider as his favorite secondary offering. The results in a small sample were incredibly successful with a 78.8% strikeout rate and a -68 wRC+ against in 2018. Alexander would greatly benefit by utilizing the slider similar to how he used it in the 2015 and 2016 seasons.
Don’t let the negative pitch value fool you; in a limited sample, Alexander’s changeup is very effective as a secondary offspeed pitch. Alexander increased the arm-side run in 2018 which resulted in a chase rate of over 50%. Damage has been done against the changeup when thrown in the zone, so Alexander should limit its overall usage.
Alexander rarely utilizes his four-seam fastball, as the sinker is Alexander’s bread and butter pitch. The four-seam did not obtain a swing outside the zone or a swing and miss in 17 pitches in 2018. Alexander does not need a fourth pitch now that he’s been able to successfully reintroduce the slider.
