Scouting Report: Robbie Glendinning
Chicago Cubs | SS
Overall
Summary
Robby Snelling, a top-5 left-handed pitching prospect (ranked 29th-33rd overall), suffered a UCL sprain in his left elbow just five days after his MLB debut on May 8, 2026. In his debut against Washington, he allowed 3 runs over 5 innings with 4 walks and 2 strikeouts. The injury was discovered after a bullpen session on May 13. Snelling is placed on the 15-day IL with an undetermined severity; Tommy John surgery may be required, which could sideline him for the remainder of 2026 and potentially most of 2027. Prior to his call-up, Snelling dominated Triple-A with a 1.86 ERA, 44 strikeouts in 29 innings, and a .116 batting average against over 6 starts.
