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

RHP/OF Ronnie Willenbrink (Affton, 2023) is an uncommitted soon-to-be senior with twitchy arm strength that stood out at Wednesday’s event. Willenbrink recorded the hardest throw home from the outfield, peppering his target with lively bullets before uncorking an 87 mph max, and he fired the day’s hardest fastball on the hill too by also reaching an 87 mph high. Though he’s still developing feel to spin his breaking ball, Willenbrink’s raw spin data is a key building block, ripping a handful of hooks at 2,300+ RPM. He’s an upside athlete with twitch and lively stuff that’s still on the market.
