Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Grunkemeyer has continued to rise up the 2024 rankings during this season after multiple strong performances this summer, including a strong outing on the mound at TPG. A durable, 6-foot-2, 205 pounder - Grunkemeyer attacks hitters from a low 3/4 slot with a fastball at 86-89 mph with both ride & run. A strike-thrower, Grunkemeyer has an above-average changeup that plays well off the fastball at 77-79 mph to go along with developing feel for a 70-73 mph slider.
