A devastating complement to his sinker, Graterol’s slider averaged 88 mph and was used around 30% of the time. With 8.4 inches of break which is 133% more than the average slider in 2019 he pitch levied a 16.3% swing-strike rate against batters, resulting in a 30% K-rate.
Amed with a 70-grade, 100mph fastball, this pitch doesn’t have as much life to it as you would like for something with so much potential. While it was a small-sample of 17 pitches , when batters swung they made contact, so Graterol will have to use this carefully to be effective.
Graterol only threw a changeup three times in 2019, for a minuscule 2% usage. As one of those got hammered for a home run, its pointless paying attention to the atrocious numbers against the pitch. Thrown at 90.9 mph, the changeup is near major-league average in both drop and break.
