BOSTON (AP) -- The Boston Red Sox placed reliever Keith Foulke on the 15-day disabled list on Tuesday and activated Mike Timlin.
Foulke, who is 2-1 with a 5.63 ERA in 29 appearances with the Red Sox this season, went on the DL retroactive to Monday. He had an MRI on his elbow on Tuesday and manager Terry Francona said he expected to have the results back on Wednesday. Right now, the team is calling Foulke's injury elbow tendinitis.
"I have a feeling that it's been developing," Francona said before the Red Sox opened a three-game series in Minnesota against the Twins. "He didn't say anything to anybody, but my guess is that it's been bothering him on and off. That's just my guess. I don't think these types of things just creep up after an inning."
Timlin was put on the disabled list on May 26 with a right shoulder strain after going 3-0 with a 1.40 ERA in 21 appearances this season.
"Getting Timlin back will really help," Francona said. "It gives us a couple guys at the end you can kind of point to. He's been so consistent -- you know what you're getting, which is huge."
Boston also recalled right-hander Jermaine Van Buren from Triple-A Pawtucket and sent right-hander David Pauley to Pawtucket after Sunday's game.
Van Buren is 1-0 with a 6.23 ERA in five relief appearances with the Red Sox and 2-0 with a 1.47 ERA and seven saves in Pawtucket.
