The sinker is Solis’ primary pitch. While the pitch allowed a wRC+ of 131, Solis was able to use the pitch as a strike-getter, but also got swings outside the zone, which is unique. Given the below-average contact rates against this pitch, Solis should continue to feature this pitch going forward.
Solis utilizes his curveball as his primary strikeout pitch. Solis added three inches of drop on this pitch and significantly increased his whiff rate. The results were not great, but were bloated thanks to an unreasonable .500 BABIP. Solis should see much better results in 2019 given the additional vertical drop.
The changeup is Solis’ secondary offspeed pitch and, much like the curveball, can get swings and misses. However, Solis did not feature the changeup as a putaway pitch. It does get ground balls, but was not very effective with a .333 batting average against in 2018.
