The Red Sox have sent veteran reliever Hansel Robles out on a rehab assignment with Triple-A Worcester, per his transactions log on MLB.com.
Robles was initially placed on the 15-day injured list because of back spasms on May 28. Since his stint on the IL was backdated to May 25, though, the right-hander is eligible to be activated as soon as this Thursday.
The plan was to have Robles make an appearance for the WooSox in their game against the Buffalo Bisons at Sahlen Field on Tuesday, but that contest has since been postponed due to rain and will be made up as part of a single-admission doubleheader on Wednesday.
If Robles does pitch for Worcester during Wednesday’s twin bill, it seems unlikely that he would be activated for Thursday’s series finale against the Angels in Anaheim. That is just speculation, though, as Robles could re-join the Red Sox without having pitched for the WooSox at all.
Prior to being placed on the injured list, the 31-year-old had made 16 relief outings for Boston this season, posting a 2.65 ERA and 5.20 FIP with 11 strikeouts to six walks over 17 innings of work.
