Super 60: Wisconsin Takeaways

Dominic Santarelli 1B / St. Joseph, WI / 2026

Super 60: What has seemingly become routine at this point the display of effortless power that was generated by the left-handed bat of Santarelli continues to impress. A physical specimen with sneaky athleticism that could help Santarelli transition to the outfield that would only raise the stock for one of the top prep bats in the class. 

From Shooter’s Stock Report: Super 60 (Position Players): “There was, once again, no shortage of effortless power on display as Santarelli belted balls up to 110.1 mph with a 102.7 avg. Featuring a max distance of 404 ft., it was almost a routine performance from one of the class’ preeminent power prospects, but one that came with hardly a drip of sweat and an inherent professional feel. The one adjustment that stood out from the summer circuit and Prep Baseball All-American Game in September, was a less pronounced drift to the front side. That small accommodation might (incredibly) unlock even more power from the imposing 6-foot, 225-pounder. While he showcased more of a below average arm in the outfield portion, the fact that he moved around at a position outside of first base was important to see, and his potential to add a corner outfield possibility might, ultimately, help raise his already high stock.”

Tyson Grulkowski RHP / Muskego, WI / 2026

Super 60: May have thrown the best ‘pen of the entire day. Grulkowski continues to make loud statements on big stages across every opportunity, looking every bit of a starter physically with a clean delivery and a clean low-effort arm action to pair. The repertoire and release are truly unique as well with a number of potential swing-and-miss options on top of some expected velocity gains to come down the line.

From Shooter’s Stock Report: Super 60 (Pitching): “The Prep Baseball All-American checked all the boxes of a spring helium prospect with his performance in Chicago at the 24th annual Super 60. With what appeared to be 10 pounds of added muscle, the 6-foot-5, 235-pound right-hander displayed a true workhorse frame including tree trunk legs with room to develop even further. Hopping on the mound with a low-pulse intensity to the session, the big right-hander sat 92-94 (2481 rpm max) from an impossibly low slot while exhibiting ride and run on a fastball that will almost certainly tick up as the spring warms up. Less pinpoint than in previous looks, it provided an opportunity for scouts in attendance to hone in on the fierce tunnel-vision expectancy of success that the competitive Grulkowski carries on the mound. The delivery is clean and repeatable with quality use of that strong lower-half in gliding strong down the mound while allowing a loose, continuous arm to work with ease. His secondary offerings, both the firmer slider at 81-82 (2917 rpm max) and slightly more depth driven curveball at 77-78 (2833 rpm max), demonstrated his innate ability for spin, and promised a future wipeout pitch in the making. Still more, Grulkowski tossed in a power-changeup at 85-86 that seemed to mirror the fastball but with perhaps slightly more sink late. In total, Grulkowski continued to ride the helium of the summer and early fall, and this look provided an avenue for jumping into a near tier 1 position.”

Jace Mataczynski SS / Hudson, WI / 2026

Super 60: Entered the Super 60 after making a name for himself late summer and into the fall. Standing at a trim 6-foot-4, 193-pounds with sloped shoulders and clear room to continue to add to his frame without sacrificing any additional athleticism. Looked the part at short among some other high-end shortstop prospects while showing off more than enough arm strength (T97 mph) to play on that side of the diamond, and did it in the midst of basketball season. Continues to find barrels at the plate and the impact continues to tick up reaching a max exit velocity of 105.2 mph with a max batted ball distance of 400 feet from an athletic and improving right handed swing. An exciting profile from a cold weather state that could show even more improvements once the spring gets started in about two months time.

Colton Semmelmann LHP / Brookfield Central, WI / 2026

Super 60: Starters look from a still projectable 6-foot-2, 205-pound frame. Confident and comfortable look on the mound, repeating a clean and athletic delivery down the mound with feel to locate three pitches. Upside arsenal with some history of in-game success against either handed batters with all three options. It was a quality showing for an arm that still has two months until his high school season starts.

From Shooter’s Stock Report: Super 60 (Pitching): “Semmelmann turned in one of the better start-to-finish bullpens of any arm at the event. The 6-foot-1, 190-pound southpaw, who features some strength in the lower-half of an otherwise wire frame, comfortably poured in strikes with three pitches while showcasing a loose ¾ arm. Working 90-92 while pulling down at an average IVB of 17.1, the fastball featured ride&run at the bottom of the zone with a likely chance to see fast upticks in velocity throughout the spring. Countering with a tighter curveball at 77-79 with more horizontal shape than depth (2698 rpm avg), he demonstrated feel in the zone, and there is a chance that it ultimately morphs into a firmer slider. Finally, the changeup profiled well next to the fastball as he killed spin at 81-84 with the ingredients of a future above average offering. It was a true starter look at the Wisconsin native, and one that positioned him into an earlier Day 2 upside with a strong spring.”

Ben Kuglitsch OF / Muskego, WI / 2026

Super 60: Physical specimen, athletically can be considered one of the top in the class standing at a lean 6-foot-2, 186-pounds with wiry strength and clear room to continue to fill into his frame. Plus or better run tool that translates out of the box and in the outfield. Defensively there’s a ceiling of an above average or better defender in center to pair as well with arm strength up to 97 mph. Quick right-handed swing with feel for the barrel and drove the ball on a line and in the air throughout both rounds of batting practice, the power has steadily ticked up throughout his prep career and continued to do so reaching a max exit velocity of 100.9 mph with more impact seemingly to come as he fills into the frame.

Ezra Liggon OF / Vel Phillips Memorial, WI / 2026

Super 60: Another high-end athlete with a ceiling physically standing at a long limbed 6-foot-4, 195-pounds with lean strength throughout the frame. At the plate the left-handed hitter was on the barrel with ticked up bat strength and speed throughout both rounds reaching a max exit velocity of 104.9 mph with plenty more impact coming as he matures into his frame. Defensively in the outfield Liggon looked the part of a potential above average or better defender with easy range and arm strength up to 95 mph. It’s easy to fall in love with the ceiling and the performance certainly got his named circled among scouts in attendance and should continue to receive attention from scouts leading up to the MLB Draft this summer.

Jack Brenner C / Fond du Lac, WI / 2026

Super 60: Twitchy athlete, standing in at a cut 6-foot, 181-pounds with twitchy strength and room to continue to fill in. Athletic right-handed swing with clear bat speed and twitch, the power had ticked up in a big way along with the barrel accuracy reaching a max exit velocity of 102.3 mph with repeated line drive contact through the middle of the field. Defensively the athleticism translated behind the plate during pens and the defensive portion of the workout, showing clean glove to hand with accurate throws and arm strength up to 82 mph with the ability to find the pocket cleanly against velo and spin in a tough environment for catchers.

Maddux Lessard C / Muskego, WI / 2026

Super 60: Physical 6-foot-1, 204-pound right-handed catching prospect with a powerful barrel. The right-handed hitter made repeated elevated contact throughout batting practice with clear bat speed and feel to drive the ball, reached a max exit velocity 100.5 mph throughout the round with loud contact during each round. Defensively behind the plate the athleticism showed in flashes along with a strong arm up to 82 mph from the crouch and pop times from 1.95-2.15 seconds.
