Dead weight

Sinker grades 79 and gets below-average expected results on 16% usage. Against all hitters, moving about 7 of every 100 pitches to the cutter (113 Stuff), about 45% of his sinkers to them, is worth an estimated 1.4 runs per season, after a 50% haircut for diminishing returns. vs. lefties: the cutter is worth +2.0 runs per 100 pitches more, 2.6 standard errors (384 and 147 pitches; his own results against that side combined with Stuff and the league’s platoon split). vs. righties: the cutter is worth +2.1 runs per 100 pitches more, 2.7 standard errors (333 and 157 pitches; his own results against that side combined with Stuff and the league’s platoon split). His fastballs stay at 35%+.

Weak pitch to watch

Four-seam grades 86 with below-average expected results; his cutter grades 113. The best case is against righties: the cutter is worth +2.3 runs per 100 pitches more, 2.9 standard errors (333 and 64 pitches), short of the 2 needed. No mix change until it clears.

Pitch idea (fragile)

Built from his own fastball (91.6 mph) plus the typical shape 15 pitchers with his slot (44°) throw: a changeup around 83.4 mph, 3.3″ rise, +18.4″ arm-side. On the same model it grades +29 against his splitter, the pitch with the same job (+21 to +34 across the production and three cross-fit models), about 111 on his splitter’s scale; the comps’ own changeups grade 92 at the median, so that sits above 93% of them. That would out-grade 100% of the comps’ real pitches, more likely a result of how the pitch was built than of the pitch, so it isn’t queued.
