The Red Sox made a series of roster moves Thursday morning, most notably reinstating right-handed reliever Justin Slaten from the 60-day IL. That move brings Boston's 40-man roster to capacity. They'd previously had a vacancy after outrighting infielder Abraham Toro. The Red Sox also activated outfielder Rob Refsnyder from the 10-day injured list. To open active roster spots for Slaten and Refsnyder, they optioned southpaw Jovani Moran to Triple-A Worcester and placed first baseman Nathaniel Lowe on the paternity list.
