A mid-80s changeup was all but nonexistent last season. We’ll see if it gets dropped from his repertoire in 2020.
Tarpley has only thrown the deuce 24 times at the big league level. It’s tough to know what he’s working with.
Tarpley mixes a traditional 4-seamer with a sinker, throwing both in the low to mid 90s. His sinker was absolutely punished last season, to the tune of a wOBA north of .600. The 4-seamer was better, but still returned a wOBA of .406. Not good.
Tarpley’s slider is the most effective pitch in his arsenal, boasting a 21.9% swinging-strike rate. His whiff gains come from an improved O-Swing percentage, up ten ticks to 40.3% in 2019.
Tarpley’s most used offering at 40.5%. It was effective at keeping the ball on the ground with an average launch angle of five. It had a whiff rate of 19.2%.
Tarpley featured his slider mostly to lefties (36/40), and it was reasonably effective with a 35.3% whiff and 30.4% chase rate.
Tarpley’s four-seamer averaged 93.4 mph had a 27.4% whiff rate and was hit hard in a very, very small sample to the tune of a .613 wOBA and .667 batting average allowed.
His curveball, which he threw 16 times in all (10.5%) and mostly to righties (13.16), had a whiff rate of 50% and a 33.3% chase rate.
The lefty Tarpley only threw nine innings in 2018 so we don’t have much to look at here unfortunately. He threw his changeup five times in all (3.3%) and all against righties. It did not record a swing and miss or allow a hit.
