August 18, 2025 4:34 PM : Slaten (shoulder) will begin a rehab assignment with Triple-A Worcester on Tuesday, Ian Browne of MLB.com reports.
Analysis: Slaten had been scheduled to throw a live batting practice session Monday. However, he's feeling good enough that the Red Sox have opted to have him skip that session in order to send him out on a rehab assignment right away. Slaten has been shelved since early June with right shoulder inflammation, so he'll likely need multiple appearances in the minors before making his return to the Boston bullpen.
