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.

6/24/25
Glowski, a 6-foot athlete, showed a higher-intent look with his heater playing at 86-89, touching 90 on his best bullet. The fastball plays with more-control than command, but the mid-70s slider is pitch that made him stand out. The slider looks the part of a potential-plus pitch, spinning north of 2700 routinely, and missing bats in an ugly fashion.

Glowski is a 5-foot-10, 165 pounder with some projection still left in a leaner frame. His stuff is solid for the age already, pitching at 84-86 mph with his fastball and showing a potential swing-and-miss breaking ball that played with two-plane shape and spun over 2400 on average at 72-75. He showed a 78-82 change that is still in the developing stages. The arm stands out most here, it is a full circle, fast arm that released from a high 3/4 slot. The delivery is up-tempo and aggressive, a bit out of control at times, leading to sporadic command.
