Hammel’s two-seamer usage increased by 14.5%, but the -14.6 pVal did not provide the results he was looking for. The pitch was very hittable, sporting a 92.5% Z-Contact rate along with a .357 BAA and .412 wOBA.

Hammel’s primary offspeed pitch saw the worst results of his career. The 90.0 Z-Contact%, 14.1 SwStr%, 23.0 K%, and .288 BAA were all four-year worsts, which culminated in a -7.2 pVal, the worst of his career.

Hammel’s change in pitch mix saw him cut the number of four-seamers he threw by more than half, and the results really ticked up (0.5 pVal in 800 pitches in 2017, 2.7 pVal in 284 pitches in 2018). He saw a dramatic increase in SwStr% and K% as well as a decrease in BAA.

For the third year in a row, Hammel’s curveball was subpar, producing a pVal of -3.2. With a 4.4 SwStr% and a 14.3 O-swing%, the pitch didn’t fool anyone, and it got hit really hard to the tune of a .353 ISO and .466 wOBA. Knowing the results, it’s no surprise that Hammel has reduced the usage of the pitch over the past three years.

Hammel used his changeup sparingly, and that was for the best. The combination of a 4.3 K% along with a 47.6 LD% produced a .409 BAA and .452 wOBA.
