With the fall season coming to a close, our staff will take some time to highlight several uncommitted prospects over the next few weeks as we prepare to enter the baseball off-season and throughout. These players have all impressed our staff recently, whether it be at events, tournaments, or other up-close looks via our boots-on-the-ground coverage.

Today we'll shine some light on RHP Ronnie Willenbrink (Affton, 2023), who is a twitchy, athletic right-handed arm that popped at the St. Louis Open this summer. There, Willenbrink recorded the hardest fastball of all the arms in attendance and repeatedly spun a slider that flashed swing-and-miss spin. Here's a nugget on him from that June event: 

"...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."
