On the mound, Roger Clemens works with a 5-pitch arsenal led by a 99 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 79 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Outlier I from a total of 4 quirks.

DiamondOps grades each pitch in Roger Clemens's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), Splitter (A), and Curveball (B). 3 of them grade S-tier, which is what separates a genuine out-pitch mix from a deep-but-flat arsenal. Its strongest tunnel pairing is the 4-Seam Fastball off the Sinker, so the two share a release look. Its 99 mph 4-Seam Fastball adds a velocity bonus on top. Arsenal grades are the same at every difficulty — unlike a hitter's OpScore, a pitch mix does not re-weight as you climb.

On the Diamond Dynasty market, Roger Clemens currently buys for about 75,093 stubs, with sell orders near 62,280 stubs. Over the past 7 days the buy price has climbed roughly 25%.
