CHICAGO –– An under-the-radar White Sox prospect received a notable accolade on Thursday.

Pitcher Fabian Ysalla was named a 2025 Rookie Level All-Star after his performances with the Arizona Complex League White Sox. The All-Star team features 16 players, and Ysalla was one of four starting pitchers to earn a spot on the roster.

Ysalla is a 6-foot, 161-pound right-handed pitcher, who signed with the White Sox on Jan. 15, 2023 as an international free agent out of Tumero, Venezuela. Through 12 starts and 10 appearances, he recorded a 2.02 ERA and a 1.16 WHIP with 40 strikeouts and 16 walks in 49 innings. He also had a 4-0 record and six scoreless appearances.

That effort earned Ysalla promotion to the Single-A Kannapolis Cannon Ballers. He has made one relief appearance since then, finishing with three innings, two hits, one unearned run, zero earned runs, two walks and one strikeout.

Ysalla is not ranked among the White Sox top-30 prospects by MLB Pipeline, but he's still just 20 years old in his third professional season. In 2024, he pitched for the Dominican Summer League White Sox and registered a 3.79 ERA and a 1.54 WHIP across 15 appearances and 35.2 innings with 24 strikeouts and 14 walks.
