Hader rarely turns to his changeup, only using it 0.42% of the time in 2019. Given the overwhelming success of his fastball and slider combination, it’s unlikely to see more of this pitch in 2020.
Hader’s four-seamer, for me, is the best in baseball. He threw it over a thousand times in 2019 at an everage velocity of 95.5 mph. It is a pure weapon. Batters hit a measly .167 off it and Hader racked up the Ks with a staggering 48.9 K%.
Honestly, his slider might be an even better pitch. A 52.3 K% meant hitters slashed a meagre .070 against his slider. That’s 3 hits, only one was a homer.
What else can you say? Hader’s four-seamer was phenomenal. It had a 36.4% whiff rate (17.5% swinging-strike rate), 57% zone rate and shut down opposing hitters to a .232 wOBA and .130 batting average. Hader had particularly big success when using it up in the zone. Quite simply it was one of the best fastballs of 2018 with a 19.7 pVal.
Hader’s slider was excellent. He just about doubled its usage from 11.3 % in 2017 to 20.7% in 2018. It had a 39.3% chase rate, 35.9% zone rate and a disgusting 25.6% swinging-K rate (54.5% whiff rate). If hitters were lucky enough to make contact the results were not too good as it allowed a meager .162 wOBA and a .138 batting average (just 8 hits allowed off the slider all year- no home runs).
There is not too much to say about the sinker as it was barely used at just 1.7% (23 total pitches). It allowed the highest wOBA and batting average of all three of his pitches at .277 and .167, respectively, which is just a testament to how unhittable he was in 2018.
