Thompson threw more offspeed pitches than fastballs in 2018, and his changeup was the pitch he threw the most. While he did struggle to throw the pitch in the zone (22.5 zone%), he got excellent results on the pitch. Highlighted by a 72.7 GB%, 50.0 O-swing%, and a .167 BAA, Thompson’s changeup earned a 1.2 pVal in a pretty small sample size.
Thompson’s second-most frequently thrown pitch was his slider, which had some mixed results. Overall, it ended up with decent outcomes, featuring a .176 BAA and a 40.0 IFFB%, but the 5.5 SwStr% doesn’t match the 25.0 K%.
Pretty small sample on his four-seam fastball, but Thompson pounded the zone with the pitch (65.6 Zone%) and allowed a .143 BAA.
Thompson’s two-seamer got hit pretty hard in 2018. The pitch allowed a .333 BAA but did have a 57.1 GB%, 57.4 Zone%, and got 8.2 SwStr% despite not having any strikeouts via the pitch.
