Blue Jays reliever Erik Swanson is dealing with a median nerve entrapment in his throwing arm, as the Jays announced to MLB.com’s Keegan Matheson and other reporters yesterday. Swanson received a cortisone shot to deal with the issue, and won’t throw for a few days while the shot takes effect.
It still seems likely that this setback is enough to put Swanson on the injured list at the beginning of the season, as was related last week when Swanson reported discomfort in his throwing elbow. An MRI came back clean without any sign of structural damage, so Swanson has at least avoided any kind of longer-term elbow problem.
A median nerve entrapment (which is related to carpal tunnel syndrome) isn’t exactly a small matter since nerve issues have no set recovery timeline. On the plus side, there hasn’t been any indication that Swanson might miss any great amount of time, even if a more concrete plan might not be known until the right-hander starts throwing again.
Acquired from the Mariners in the 2022-2023 offseason, Swanson was outstanding in his first year in Toronto, but injuries contributed to a rough start to his 2024 campaign. Swanson dealt with some forearm tightness during last year’s Spring Training and a subsequent IL stint delayed his start to the season, and he then struggled so badly over his first 18 appearances that he was sent to Triple-A. Swanson returned to the big leagues after the All-Star break and then seemed like his old self, making for some rather glaring splits — a 9.20 ERA in 14 2/3 innings in the first half and a 2.55 ERA over 24 2/3 frames in the second half.
Given the dismal state of Toronto’s bullpen last season, the Blue Jays badly need Swanson to stay healthy and fully bounce back to his past form as a key setup man. New signing Jeff Hoffman looks to be in line for the closer’s job, with Chad Green, Yimi Garcia, Nick Sandlin, and Swanson all lined up for high-leverage work.
