Roloff

Roloff started his impressive day off with a clean ‘pen. Standing at a projectable 5-foot-10, 160-pounds Roloff is an athletic, free mover downhill and he pairs it with a loose, whippy arm. During his ‘pen he ran his fastball up to 84.3 mph and this is a pitch that plays with life/carry through the zone, roughly 14’ of IVB on average. Roloff also showed a refined feel for three different offspeed pitches, the first being a low-70s curveball with downer action. He also spun in a mid-70s slider with tight 11/5 break. Behind the plate, Roloff is an advanced receiver and is quick out of the crouch that recorded pop-times in the 1.93-2.06 range. Offensively, Roloff features a smooth left-handed swing that is short and quick to the ball, and he registered exit velocities up to 86.4 mph. 

Roloff is a savvy left-handed-hitting catching prospect in Wisconsin’s junior class and across the summer and fall, he consistently showed well in front of our staff. Listed at an athletic 5-foot-10, 155-pounds, Roloff’s advanced defensive capabilities point to him sticking behind the plate in the long run as he has created lows of 1.93 pop times in front of our staff before. Roloff is actually somewhat new to the position, which is even more impressive, and he’s also looked like a natural at second base and in the outfield in front of us. Offensively, his hit tool is also something that sets him apart from his peers, as he consistently drives the ball hard to the entire field. Overall, Roloff has really made a name for himself inside this class after a productive 2022 campaign and he is a name to keep a close eye on as continue his high school career.

Roloff has blossomed into a real prospect in the state, as an athletic and versatile player with two-way potential. While he just caught and played the outfield at this event, you’d never know that Roloff is somewhat new to both positions. Behind the plate, he’s quick-twitch both inside of his transfer as well as out of the crouch defending his position on the bunt attempt. That quickness resulted in a pop range of 1.94-2.00 with 76 mph arm strength, and as you might expect, his athleticism and arm strength worked in the outfield too. There, he topped 85 mph to home and roamed the outfield grass smoothly, with above-average foot speed, measured at 19.2 mph during his 60-yard dash (7.25). Roloff’s left-handed bat is equally athletic, and he’s gained significant strength since he appeared at a March event. Here, Roloff reached a max exit speed over 90 mph – and given his presently slight 5-foot-10, 155-pound build – signals a bright future at the plate as well.
