Garrett’s fastball has become his secondary offering. He dropped its usage by over 10% in favor of his slider. It’s a good move for Garrett, but his heater averages over 95 mph and can touch 99 mph at its peak. It’s relatively straight, and mistakes get punished. Garrett’s success lies within his slider, not his fastball.
They say the reason the brawl between the Pirates and the Reds happened was because the Pirates said Garrett’s slider was TOO GOOD (they in fact do not say this). You should believe it though, as he too realized this and upped its usage to 58% in 2019, getting a swinging-strike one in every four (yes that’s right) and striking out 68 of his 76 strikeouts on it. Easily one of the best pitches in baseball.
Garrett’s fastball averaged 95 mph in 2018 and serves as his most-featured option of his repertoire. Opposing batters hit .308 against the pitch while slugging .511, which isn’t ideal, and it’s clear that it wasn’t an effective pitch for him. It was worth a -2.6 pVal.
Garrett’s 83.6 mph slider is his best pitch, and he threw it about 33.37% of the time in 2018. It generates plenty of swings and misses as evidenced by a 26.1% swinging-strike rate, and it held opposing batters to just a .111 batting average. All told, it was worth an impressive 8.2 pVal
With Garrett pitching out of the bullpen in 2018, he didn’t throw his changeup often as the clear third option. Opposing batters hit .250 against the pitch while slugging an even 1.000 as the only changeup that was put into play went for a home run. The pitch does show promise with just a 50% contact rate against along with an above-average 17.1 swinging-strike rate this past year.
