Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average

‘26 RHP/1B Aidan Hartholt posted the top fastball velocity at the event at 87.5mph. Strong, sturdy frame at 6-foot-3, 205-pounds and works with a three-pitch mix. Heavy fastball that sat 85-87mph throughout the entirety of the bullpen and the breaking ball comes with some interesting characteristics. Hartholt creates a ton of depth on the pitch (-16.6 avg IVB) at 67-72mph with 99% spin efficiency. Also flashed a changeup at 78-79mph with heavy horizontal action (17.2 avg HM). Comes with size on the mound and there’s plenty to like with all three pitches in his arsenal.
