Ranking at No. 10 in the most-viewed profiles of 2024 is LHP Colton Semmelmann (Brookfield Central, 2026; South Carolina commit).
Semmelmann has truly broken out this past year, starting back on the winter circuit at the West Milwaukee Preseason ID where he ran his fastball up to 88 mph with two secondaries to pair. The athletic left-hander would go on to find continued success across each look at him in the spring and throughout the summer where he proved to be one of the top arms in the state.
Semmelmann's name circulated a lot throughout the next months leading up to the Future Games where he was one of the top arms for Team Wisconsin. At LakePoint Semmelmann would find success among some of the top 2026s in the country, running his fastball up to 90 while showing swing and miss stuff during his outings.
Semmelmann continued to elevate himself as the year progressed and solidified himself among some of the top talents in the state regardless of class.
Following a successful 2024 year which was capped off by a strong outing at the Grand Park Fall Championships, Semmelmann committed to South Carolina. The southpaw will look to lead a deep Brookfield Central rotation to build off his standout 2024.
Scouting Report
The 6-foot-1, 176-pound left-hander is one of the top pitchers in the state’s class of 2026. An athletic mover on the mound that has shown the ability to repeat his delivery across an extended outing which has helped his ability to command his pitches. His fastball got up to 87 mph early in his outing and sat 84-86 throughout. Semmelmann was able to locate his fastball to both his arm-side and glove-side in this look and earned swings-and-misses in the zone. Semmelmann was confident in his low-70s curveball that is another swing-and-miss offering for him and showed feel to throw to both sides of the plate against both handed batters. Rounding off his pitch mix Semmelmann showed a low-80s changeup that he threw to both handed batters, flashing like a potential weapon against any hitter once he gains more feel of the pitch. A rising arm in the class of ‘26 Semmelmann will be one to follow across his prep career as he matures both physically and on the mound.
