Gonsolin (elbow) is on track to start a rehab assignment with Triple-A Omaha this week, per MLB.com.
Gonsolin signed with the Royals on Aug. 13 and is nearing the final stage of his recovery from Tommy John surgery with an internal brace, which he underwent on his right elbow in August 2025. The right-hander's first outing is expected to last approximately three innings or 50 pitches. It remains to be seen how many rehab starts Kansas City plans to give him, but Gonsolin figures to receive some starting opportunities with the big-league club down the stretch in September.
