Robert Stephenson is dealing with yet another injury concern, as Angels manager Kurt Suzuki told reporters (including Jeff Fletcher of the Orange County Register) that the right-hander has sustained some type of unspecified setback during his throwing sessions. Suzuki described the issue only as “a little setback,” but Stephenson will undergo tests to determine the extent of the matter.
Given the timing of this apparent injury and Stephenson’s checkered health history, it now seems very possible that he’ll begin the season on the Angels’ 15-day injured list. Even if this current issue is just a speedbump and Stephenson is back throwing in a few days’ time, his throwing progression could be scaled back a bit, plus the reliever has yet to pitch in any Cactus League games.
In his own words, Stephenson already went into Spring Training “a little bit behind everybody” after receiving an injection during the offseason to deal with some symptoms related to thoracic outlet syndrome. Still, it was just a week ago that Stephenson was feeling confident about his chances of making the Opening Day roster, as he had progressed to facing hitters during live batting practice sessions.
It’s an unwelcome start to Stephenson’s third season with the Halos, as the right-hander has barely pitched over the first two seasons of what was initially a three-year, $33MM contract. As per a clause in the contract, the Angels gained a $2.5MM club option for 2027 because Stephenson suffered a major elbow ligament-related injury — namely the Tommy John surgery that sidelined him for the entirety of the 2024 season.
Stephenson returned to appear in two games in May 2025, but a nerve-related biceps problem forced him back to the IL for almost three more months. He made it back to pitch in 10 more games for Los Angeles before a bout of elbow inflammation ended his season. Stephenson’s Angels resume consists of just 10 innings in 2025, with a 2.70 ERA, 23.8% strikeout rate, and 7.1% walk rate.
While a small sample size, Stephenson’s solid numbers provided some hope that he could again flash the high-leverage form he showed (albeit on an inconsistent basis) in past seasons with the Reds, Rockies, Pirates, and Rays. On the other hand, the TOS symptoms provided a new injury scare, and it remains to be seen what imaging might reveal about this latest situation.
In better news for the Angels’ relief corps, Fletcher writes that Ben Joyce has added sliders to his throwing repertoire during bullpen sessions, and minor league signing Nick Sandlin is expected to soon move into game action after a pair of live BP sessions. One of the highest-velocity pitchers in baseball, Joyce had a seeming breakout season in 2024, but missed almost all of 2025 due to shoulder surgery. Sandlin also barely pitched in 2025, as a lat strain and elbow inflammation limited him to 16 1/3 innings with the Blue Jays.

In a related story, Stephenson has been spotted on several occasions meeting with Anthony Rendon.
If there’s a more useless set of free agents on one ballclub, I’d like to hear about it.
Ohtani saves them, but it looks like he just wanted to play in SoCal and the Dodgers didn’t have a DH at the time.
At this point, I don’t even think the 2.5 mil option for next season is all that enticing. Even for the Angels…
@halosfan8. Yeah arte doesn’t like pitchers that pitch every 5 days. What about the one that’s only pitched 12 innings. 2.5 mil is steep.
Hes got a better chance of retirement than pitching a full season again.
Ron, is the picture accompanying your name of Don Mossi?
@ron tingley. He probably has T.O.S. he said he caught it before damage was done it was in a article, but literally every time spring training starts he’s down with arm tightness or numbness. One healthy year and literally the same crap his whole career his arm is toast.
Im pretty sure i was happy with Stephenson’s signing a few years ago. In hindsight… sheesh.
I think he just needs to to retire because he’s never going to be fully healthy again.
