TOS Symptoms Again This Offseason. Still Targeting Opening Day. Still Fragile.
Robert Stephenson's late-2025 stretch with the Angels was genuinely excellent — a 2.70 ERA across 12 outings, swing-and-miss stuff, the kind of performance that makes a manager want to use him in high-leverage situations. The arm talent is real. The question is always the same one with Stephenson: how long can it last?
He dealt with nerve issues and thoracic outlet syndrome symptoms again this offseason. He said he feels good now, that he is back to throwing, and that he will be ready for Opening Day — though he acknowledged he is about a week behind the other pitchers coming out of camp. That is the familiar Stephenson pattern: encouragement followed by a qualifier, a qualifier followed by more encouragement. He has thrown 12 games over the last two seasons combined. That number needs to improve dramatically for him to be anything other than a depth option.
Thoracic outlet syndrome is a structural condition. It does not resolve between seasons the way a muscle strain might — it can recur, it requires ongoing management, and it has now surfaced in back-to-back offseasons. The talent justifies keeping him on the roster. The history demands that Suzuki never counts on him being available tomorrow.
