Non-MLB
Matt Dermody has thrown 1,709 pitches that have been tracked by the PITCHf/x system between 2016 and 2024, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2024, they have relied primarily on their Curve (75mph) and Fourseam Fastball (92mph), also mixing in a Sinker (92mph) and Change (83mph).
In 2024, compared to other LHP:
Their curve has an exceptional bite, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves, has sweeping glove-side movement and has slightly below average velo. Their fourseam fastball has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their sinker generates a very high amount of groundballs compared to other pitchers' sinkers, generates fewer whiffs/swing compared to other pitchers' sinkers, has less armside run than typical and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 12 of them in 2024) dives down out of the zone and generates fewer whiffs/swing compared to other pitchers' changeups.
