BOSTON -- The Twins' bullpen saw a big shift on Wednesday, as Phil Hughes was recalled from his rehab assignment at Triple-A Rochester and Craig Breslow was placed on the 10-day disabled list with left thoracic rib cage soreness.
"Given where we're at with some guys being down because of recent usage, we needed to find a way to replenish a bit," Twins manager Paul Molitor said on Wednesday. "With Craig's situation, he's been able to pitch through this rib cage situation for the most part. ... I think it goes back to Spring Training and maybe even a history of it.
"It made sense as we head into the break for him to try and get that calmed down, and it gives Phil an opportunity to get back here in the short term."

Minnesota's bullpen was called on to pitch seven innings on Tuesday against the Red Sox after a 76-minute rain delay following the second inning. Hughes' inclusion adds a fresh arm to what looked like a depleted bullpen.
"That's going to be the biggest thing is just to be out there and be somewhat reliable and get some innings," Hughes said. "With what happened last night and the doubleheader [on Saturday], we're going to have to get innings out of some guys someway."
Hughes made three appearances for Rochester while recovering from a right biceps injury, which he says he is still managing. He was scheduled to make his final rehab outing on Wednesday before getting called up.
The right-hander said that he will stay in the Twins' bullpen for the "foreseeable future."
As for Breslow, the lefty said that going on the DL would be the most beneficial thing for Minnesota right now.
"I understand where we are, and it's probably unfair for me to say, 'Hey, give me 4-5 days off and I'll be fine,'" Breslow said.
In the interim, Breslow, who has a 5.28 ERA in 29 innings, will spend his recovery time looking to correct what has caused his recent struggles.
"I'm not going to point toward this as a reason for struggling over the last two weeks," he said. "I think I'd rather say that this is an opportunity to get completely healthy, to take a look at what has happened, and maybe devise a new strategy to face right-handed hitters."
