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

2029 Kellen Williamson (Candor Junior-Senior High School)
Williamson stands 6-1, 175 pounds with a projectable frame. Young for the environment with plenty of runway; projection remains the separator. Ran 4.10 in the 30-yard. Peak Jump: 21.0. Grip strength: 130/126. Max EV reached 91 mph. Catching arm strength showed 75 mph. Big-framed 2029 worth following.
Virkler stands 5-8, 175 pounds with a compact, strong build. Upperclass profile; tools need to show now with smaller physical projection remaining. Max EV reached 94 mph with 344 feet of distance. Ran 4.09 in the 30-yard. Grip strength: 122/122.
Pitching: Fastball 78–81 mph (T81). Spin 1863–1989 rpm. IVB 8.4 with 3.4 HB. Zone rate 33%. Breaking ball 69–70 mph. Spin 2193–2265 rpm. IVB -3.0 with -16.8 HB. Zone rate 20%. Breaking ball shape stands out most.
