Just one day after returning to the active roster, Blue Jays right-hander Jameson Taillon was placed on the 15-day injured list on Saturday with right elbow inflammation. Manager John Schneider said the team is reviewing MRI results and second opinions, acknowledging that the veteran pitcher’s season is likely over.
The optimism that accompanied Jameson Taillon back to the major leagues proved short-lived. Having spent three weeks sidelined starting August 11 with right forearm tendinitis, the 34-year-old right-hander felt comfortable through a Triple-A rehab assignment and returned to the big leagues for Friday night’s start against the Kansas City Royals.
That return lasted all of two innings and 29 pitches. Taillon allowed one earned run on a solo home run by Bobby Witt Jr. before exiting the game with right elbow discomfort after just two frames. The quick departure forced manager John Schneider out of the dugout to speak with the umpires between innings while the bullpen hurried to stir.
Medical Uncertainty and the Likelihood of a Lost Season
Any hint of elbow trouble carries heavy significance for Taillon, who has twice undergone Tommy John surgery during his 10-year major league career. While Taillon initially told Schneider that the discomfort felt more like a nerve issue than potential ligament damage, the subsequent medical imaging prompted immediate caution from the club.
“He got an MRI. We read it initially with the inflammation, but with other doctors and other opinions, we’re going to look at it and see the timeline.”

Schneider did not close the door entirely on a return, but he conceded that Taillon’s season is probably over.
A Difficult Campaign Following a Cubs Departure
The setback compounds what has been a challenging year for the veteran pitcher. After posting a 3.68 ERA across 23 starts last season, Taillon struggled to a 5.68 mark in 17 starts this year, largely driven by surrendering 25 home runs in 76 innings while with the Chicago Cubs. The Cubs designated him for assignment on July 27 before restructuring their rotation.
Acquired by Toronto as a low-cost depth option following the trade of Kevin Gausman, Taillon made just three starts for his new club. While his first two outings yielded four innings of three-run ball and four scoreless frames respectively, a noticeable velocity dip during that second start triggered his initial August absence.
Rotation Scramble and the Wild Card Chase
Taillon’s return to the shelf arrives at a delicate moment for the Blue Jays, who entered the weekend half a game behind the Cleveland Guardians for the final American League Wild Card spot. Although Toronto defeated the Royals 9-2, Cleveland’s doubleheader sweep against the Tigers pushed the gap to one full game.
The rotation depth behind ace Dylan Cease and José Soriano is now severely tested. With José Berríos (Tommy John), Cody Ponce (ACL), Bowden Francis, Shane Bieber (right teres major inflammation), and Patrick Corbin all residing on the injured list, the team faces an immediate squeeze.
| Available Rotation Options | Current Status / Notes |
|---|---|
| Dylan Cease | Pitching every fifth day down the stretch |
| José Soriano | Providing serviceable starts behind Cease |
| Max Scherzer | Utilized when feeling strong |
| Spencer Arrighetti | Carrying a 4.82 ERA, deployed as bulk bullpen arm |
Tracking Trey Yesavage’s Recovery Timeline
With rotation options running thin, attention turns rapidly toward the minor league recovery pipeline. Twenty-three-year-old Trey Yesavage, who underwent surgery to repair a meniscus tear in his left knee, threw 23 pitches in a bullpen session at the club’s complex in Dunedin, Florida, reaching 92 mph without issue.

If Yesavage successfully navigates his next scheduled bullpen session and a subsequent two-inning simulated session facing hitters, he could factor into the team’s plans by the end of the regular season, albeit likely in shorter bursts.
Immediate Outlook on the Mound
Sunday’s series finale against Kansas City is already configured as a bullpen day, featuring Spencer Arrighetti as the bulk pitcher following an opener. As the bullpen runs on heavy workloads down the stretch, the club awaits definitive word on Taillon’s second opinions and whether reinforcements from the minor league complex can arrive in time.
