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

2025 RHP Jacob Belecky showcased one of the better fastball/curveball combinations at the tryouts but had a difficult time locating the pair. Strength on the mound at 6-foot-3, 205-pounds and it was a live fastball at 87-88mph and likes to work up in the zone with the pitch. Flashed a good, high-spin breaking ball at 71-72mph (2540 avg. spin) with a two-plane look. Works down with the breaking ball, although he had a difficult time getting strikes with it. Intriguing overall package from Belecky on the mound if he can hone in on the zone as both pitches should garner swings/misses.
