Pittsburgh Review

The concept of identifying the "best" pitch is subjective, influenced by various factors such as velocity, spin, and whiff rates. However, run value provides a useful measure by considering both results and context. For example, an out with bases loaded carries more weight than one with no runners on base.

Mitch Keller's four-seam fastball leads the Pittsburgh Pirates' staff in run value for its category. With a 9 run value, it has proven effective with a .257 batting average against it and a 24% whiff rate. Keller's versatility in adding new pitches complements his four-seamer well.

Paul Skenes' sinker stands out with an 18 run value. Although it's technically a "splinker," this sinker-splitter hybrid combines velocity and drop effectively. Skenes also makes the list for his changeup, which boasts a high whiff rate of 54.8%.

Luis Ortiz's cutter became a key pitch after struggling to develop a changeup. His focus on this pitch since April has yielded positive results, particularly against left-handed batters.

Joey Wentz's curveball showed promise despite limited innings pitched for the Pirates. With only 12 innings thrown post-waiver claim from the Tigers, his curveball had an impressive .143 batting average against it.

Hunter Stratton’s slider emerged as highly effective due to its significant movement compared to his cutter. The slider posted a notable .100 batting average against it and led in whiff rates among sliders at 43.5%.

Colin Holderman attributes his success with the sweeper to its complementary movement relative to his cutter and sinker velocities. While effective when consistent, wrist issues have occasionally affected its performance.

In September, Joey Bart likened Skenes’ changeup to Kevin Gausman's splitter-changeup combination: “It kind of reminds me of when I was young catching Kevin Gausman... So he's got 100 mph and he's got plenty of offerings to get him in the zone and put guys away.”
