Scouting Report

Scouting grades: Fastball: 55 | Slider: 55 | Changeup: 45 | Control: 45 | Overall: 40

Larson transferred from Southeast Polk HS (Pleasant Hill, Iowa) to IMG Academy (Bradenton, Fla.) for his 2024 season, becoming the best prospect at the perennial powerhouse. Yet another player to earn a seven-figure bonus from the White Sox after showcasing with their Area Code Games club, he signed for an over-slot $1,397,500 as a supplemental second-round pick Chicago acquired from the Mariners in a trade for Gregory Santos. He added 17 pounds by the end of instructional league and was set to make his pro debut in 2025 before injuring his elbow in a January minicamp and requiring Tommy John surgery.

Larson offers the potential for two plus pitches, including a fastball that presently parks at 92-94 mph and peaks at 96 with run and sink. He can spin his low-80s slider up to 3,000 rpm, giving it two-plane depth when it's on, though it can get more slurvy at times. He's just beginning to refine an upper-80s changeup that needs more action and velocity separation from his fastball.

While he struggled with his control and command on the showcase circuit, Larson made strides with harnessing his fastball and slider during his senior season. His low arm slot creates wide angle and a flat approach that create deception, though some scouts believe his mechanics and effort hamper his strike-throwing and could land him in the bullpen. He'll need time to return to health and develop but has drawn some comparisons to Max Fried and Shane McClanahan.

Larson pitched for the White Sox's Area Code Games team in August 2023, then joined the organization 11 months later as a supplemental second-round pick acquired from the Mariners in a trade for Gregory Santos. In between he transferred from Southeast Polk HS (Pleasant Hill, Iowa) and became the best prospect at perennial powerhouse IMG Academy (Bradenton, Fla.). He passed on a Texas Christian commitment to sign for an over-slot $1,397,500.

Larson operates with a 92-94 mph fastball that touches 96 with run and sink, and it should pick up more velocity once he fills out his projectable 6-foot-2 frame. His low-80s slider can reach 3,000 rpm and has two-plane depth at its best, though it can get slurvy at times. He's in the early stages of developing a changeup that's presently too firm in the upper 80s and lacks consistent action. 

After battling his command on the showcase circuit, Larson did a better job of locating his fastball and slider this spring. Some scouts believe the effort and low arm slot in his delivery present reliever risk and hamper his control, though his mechanics also create angle and a flat approach angle that enhance his deception. He’ll need time to add some polish but his biggest backers compare him to Shane McClanahan.

Larson was a high school standout in Iowa when he decided to pack his bags and head south to spend his senior year at IMG Academy. The left-hander arrived in Florida with some exciting but inconsistent stuff that was on display during the summer showcase circuit at events like the Area Code Games, and he’s taken a step forward in his year in Bradenton.

A 6-foot-3 southpaw who has a ton of ceiling, Larson has the potential to eventually have three plus pitches if they all click. With a fast and whippy arm, he already can run his fastball up to 96 mph, sitting in the 93 mph range, and it’s easy to dream on more consistent velocity as he matures. When he executes it, his 79-80 mph slider is a true out pitch with depth, registering high spin rates in the process, but it can be slurvy at times. He has a firm upper-80s changeup that he doesn’t use that often at this level, but has shown enough feel that some evaluators think it will give him a third plus offering.

Larson’s ceiling will be determined by how much he can continue to improve his control and command. It was spotty over the summer and it’s gotten better this spring, a good trend for a cold-weather player who moved for more reps and better competition. Some may have seen some reliever risk in the Texas Christian recruit in the past, but the same could be said for All-Star Shane McLanahan, who has similar stuff in some scouts' eyes.
