Silseth (elbow) allowed five earned runs on eight hits and three walks while striking out two across 4.2 innings in a rehab outing with Triple-A Salt Lake on Friday.
The surface stats aren't encouraging for Silseth, but he built up to 92 pitches. The Angels were originally expected to activate him and insert him back into the rotation this past Wednesday against the Athletics, but the big club ultimately had him make one more tune-up outing in the minors. After another poor showing Friday, Silseth has now allowed 14 earned runs across 12.1 frames with Salt Lake. The underwhelming results could cause the Angels to reassess his role in the short term, as he might be activated from the 60-day injured list and optioned to Triple-A once his 30-day rehab window draws to a close.
