Roby underwent Tommy John surgery Friday, Katie Woo and Keith Law of The Athletic report.

EDGE Analysis

Roby had landed on the 7-day injured list at Triple-A Memphis two weeks ago with an undisclosed injury, and as it turns out, he needed surgery on his pitching elbow that will likely keep him sidelined until the 2027 season. The righty had pitched well this season between Double-A Springfield and Memphis before getting hurt, collecting a 3.10 ERA and 87:19 K:BB over 78.1 innings covering 16 starts.

Triple-A Memphis placed Roby on the 7-day injured list Monday due to an unspecified injury.

EDGE Analysis

Roby has been lights out lately at Memphis, allowing just two earned runs with a 21:5 K:BB over 21 innings covering his last four starts. The Cardinals haven't provided word on the nature of his latest health concern, but Roby's injury history is lengthy, and his issues have often involved his pitching shoulder. Added to the Cardinals' 40-man roster over the offseason, Roby has posted a 3.10 ERA and 87:19 K:BB across 78.1 frames between Double-A Springfield and Memphis in 2025.

Roby has been promoted from Double-A Springfield to Triple-A Memphis.

EDGE Analysis

Roby has bounced back from last year's injury-shortened, disappointing campaign by posting a 2.49 ERA and 57:11 K:BB over 47 frames covering 10 starts with Springfield. This will be the 23-year-old first stint at the Triple-A level.

The Cardinals optioned Roby to Double-A Springfield on Wednesday.

EDGE Analysis

Roby had a nice showing this spring, allowing four runs (three earned) with a 10:2 K:BB over nine innings of work. He was never going to make the Opening Day roster, though, after another injury-shortened season in 2024. Roby has some of the best stuff among the Cardinals' pitching prospects but has totaled only 96.2 innings over the last two seasons because of arm problems.

Roby (elbow) resumed facing hitters during the Rangers' fall instructional camp and is expected to enter the 2022 minor-league season with no restrictions, Kennedi Landry of MLB.com reports.

EDGE Analysis

A 2020 draft pick who made his professional debut in 2021, Roby submitted a 2.45 ERA, 0.95 WHIP and 35:7 K:BB across 22 innings in his first six starts with Low-A Down East before he was shut down in mid-June with a right elbow strain. He was fortunate to avoid Tommy John surgery, and after treating the injury with extended rest and recovery, Roby looked dominant once again in his limited action in instructional ball, most notably tossing an immaculate inning during one of his appearances. The Rangers may send him back to Down East to begin the 2022 campaign, but if he's able to immediately pick up where he left off last year, a promotion to High-A Hickory could come quickly.
