On the mound, Greg Weissert works with a 5-pitch arsenal led by a 95 mph Sinker and a 95 mph 4-Seam Fastball. His pitching ratings include 96 Velocity, 78 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Stopper from a total of 3 quirks.

DiamondOps grades each pitch in Greg Weissert's arsenal: Slider (S), Sinker (S), 4-Seam Fastball (S), Sweeper (S), and Circle Change (A). 4 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 Sinker off the 4-Seam Fastball, so the two share a release look. Its 96 mph Sinker 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.

Greg Weissert is not currently traded on the open Diamond Dynasty market — cards like this are typically earned through programs or collections rather than bought with stubs.
