August 25, 2025 6:26 PM : Red Sox manager Alex Cora said Monday that Slaten (shoulder) probably won't require another rehab appearance before being activated from the 60-day injured list, Tim Healey of The Boston Globe reports.
Analysis: Slaten has made three rehab appearances with Triple-A Worcester, yielding just one unearned run with a 5:1 K:BB over three innings. The reliever has been shelved since late May due to right shoulder inflammation.
