St. Louis Cardinals pitching prospect Tekoah Roby (elbow) underwent Tommy John surgery and is expected to miss the entire 2026 season. The 23-year-old right-hander, acquired from Texas in the 2023 deadline deal for Jordan Montgomery, had made six starts at Triple-A Memphis after being promoted in June. Following a rough start, Roby had allowed just two earned runs over his last 21 innings before the injury. Durability remains a concern, as Roby also missed significant time in 2023. His fastball sits in the mid-90s, but his high-spin curveball is widely regarded as his most effective weapon. Continue to stash Roby in dynasty formats.

The Triple-A Memphis Redbirds placed St. Louis Cardinals right-handed pitching prospect Tekoah Roby (undisclosed) on the seven-day injured list on Monday. While Roby has dealt with shoulder injuries in the past, it's unclear if this is related. The team's No. 10 prospect, per MLB Pipeline, has gone a combined 7-4 this year with a 3.10 ERA, 1.09 WHIP and 87:19 K:BB in 78 1/3 innings over 16 starts with Double-A Springfield and Memphis. The 23-year-old had been peaking recently with Memphis, striking out 21 and walking only five while giving up two earned runs in his last four starts. Hopefully, the former third-rounder in 2020 will be able to return sooner than later. Roby relies on a mid- to upper-90s fastball with a nasty curveball that generates a lot of swings and misses. Health has been his biggest issue, and it could deny him a chance to debut in the big leagues in 2025.

St. Louis Cardinals right-handed pitching prospect Tekoah Roby struck out six batters across 5 2/3 innings of work against Triple-A Charlotte.

During this stretch, Roby has tallied 21 strikeouts while allowing just five free passes. Earlier this season, Roby logged 47 innings with Double-A and posted a 2.49 ERA with an impressive 0.96 WHIP.

We could see the right-hander make his big-league debut at some point later in the season, and he could be worth keeping an eye on in deeper formats.

St. Louis Cardinals right-handed pitching prospect Tekoah Roby has been promoted from Double-A Springfield to Triple-A Memphis. Roby, the team's No. 11 prospect per MLB Pipeline, gets the promotion after going 4-2 with a 2.49 ERA, 0.96 WHIP and 57:11 K:BB in 47 innings over 10 starts. The 23-year-old former third-rounder by the Texas Rangers in 2020 only managed 10 total starts last year due a shoulder injury, so it's nice to see him bounce back already in 2025. Roby, who stands at 6-foot-1 and 210 pounds, could make his major-league debut later this season if he impresses at Memphis. He features a fastball, nasty curveball, slider and changeup. It's nice to see him performing well this season, but the Cardinals will likely want to see him get through a whole year healthy before considering him for their rotation in 2026.
