Thrown a whopping 24 times over the course of his Major League career, we can’t gather much info on the pitch just yet. The nine times he threw it in 2018 all went for strikes. How immaculate.
A .460 wOBA came with a painful .528 BABIP in 2019, contributing to a painful-looking ERA for Williams. Some correction in batted ball luck should help the results off the heater, but it hasn’t been anything special yet.
The slider has been Williams’ best offering over the course of his young career. The pitch has averaged a tasty 24% SwStr rate and has held opposing hitters to just a .233 BAA.
Williams throws hard (95.7 mph) but throwing it 65% of the time may be a problem. He can be a bit wild with it drawing a few too many walks.
Williams is only a two-pitch pitcher so he used his slider quite often, especially in strikeout situations. He posted a 40% K rate and a 26% whiff rate on a pitch that only saw batters making contact 41% of the time.
