According to a league source, the Red Sox claimed pitcher J.D. Durbin from the Arizona Diamondbacks this afternoon.
Durbin, 25, was among the Minnesota Twins' final cuts during spring training.
In the Diamondbacks' battle with the Colorado Rockies last week, Durbin pitched two-thirds of an inning, giving up seven earned runs on seven hits.
With the pickup, the Red Sox may have to make one or two roster moves when they are also expected to activate pitcher Mike Timlin off the disabled list.
Editor's update, 4:10 p.m.: The Red Sox confirmed this transaction in an afternoon press release.
