Game Performance

Notes

Comments

3/03/24
Thomson owns an athletic, projectable, 6-foot-4, 195 pound frame paired with some of the best command in the class. Despite being in the middle of basketball season, Kellen sat 87-88, T 88.8 mph on his fastball, a tick compared to looks in the fall. His sinker worked with 17.4" of horizontal break, on average, and pairs very well with his ability to 'pull-the-string' on an 80-81 mph changeup, a pitch that will be a real weapon against left-handed hitters. The slider is an above average offering, spinning at 75-77 mph with late bite. We prioritize starter profiles within our rankings and Thomson certaintly fits that mold with his frame, athleticism, command, and a well-rounded four-pitch mix.
