Johan Oviedo (elbow) will start for Triple-A Worcester on Thursday

Oviedo has been on the 60-day injured list since March with a right elbow strain but has been inching closer to a return. His start on Thursday will be as an opener for John Holobetz, so Oviedo is unlikely to pitch more than one inning, but he does have a few weeks to present himself as a potential bullpen option for the Red Sox in the playoffs.
