Boston Red Sox
Greg Weissert has thrown 1,643 pitches that have been tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (81mph), Sinker (94mph) and Fourseam Fastball (94mph). He also rarely throws a Change (84mph).
In 2024, compared to other RHP:
Their slider sweeps across the zone, has below average velo and has some two-plane movement. Their sinker has heavy sinking action, results in more flyballs compared to other pitchers' sinkers, has slight armside run and has slightly above average velo. Their fourseam fastball has heavy sinking action, results in more flyballs compared to other pitchers' fourseamers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 10 of them in 2024) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
