Larson (elbow) has allowed four unearned runs on three hits and one walk while striking out five over 2.2 innings through his first two starts in the rookie-level Arizona Complex League.
The pair of appearances are Larson's first in the professional ranks, as the 20-year-old lefty didn't pitch after being drafted out of high school in 2024, then missed the entire 2025 campaign after undergoing Tommy John surgery in February of that year. Prior to undergoing surgery, Larson's fastball sat around 93-to-94 mph, but velocity readings from his two starts in the ACL haven't been made available.

White Sox's Blake Larson: On mend from Tommy John surgery
Rotowire
Larson had Tommy John surgery in January, MLB Pipeline reports.
Larson, the No. 68 overall pick in last year's draft, added 17 pounds of muscle by the end of fall instructs and was set to make his official pro debut this year before injuring his elbow during a January minicamp. His fastball and slider each have plus potential and Larson could continue to throw harder as he fills out his 6-foot-2, 180-pound frame, assuming he makes a full recovery. Given the timing of the surgery, Larson could be ready to pitch early in the 2026 season.
