Dead weight

Sinker grades 85 and gets below-average expected results on 22% usage. Against righties, moving about 11 of every 100 pitches to the sweeper (118 Stuff), about 40% of his sinkers to them, is worth an estimated 0.6 runs per season, after a 50% haircut for diminishing returns. vs. righties: the sweeper is worth +2.2 runs per 100 pitches more, 2.7 standard errors (157 and 132 pitches; his own results against that side combined with Stuff and the league’s platoon split). His fastballs stay at 35%+.
