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.

RHP/INF Jack Olson (Viroqua, 2026) stands at a long-levered, 6-foot-2, 165-pound frame with plenty of room for added strength. His fastball comes out easy, topping at 84.7 mph with life through the zone. Olson features a four-pitch mix, including a curveball, slider, and changeup, complementing his fastball well. He moves loosely and easily down the mound, and his physical projection makes him an intriguing follow in the 2026 class. Olson also showed off some power at the plate, possessing loose hands that stayed on the barrel for a 91.8 mph max exit velocity.
