The Twins optioned righthander Jeff Manship to Class AAA Rochester and recalled righthander Kyle Waldrop following Wednesday's 12-5 loss to the White Sox.

Manship yielded three earned runs in the sixth inning, raising his ERA to 10.97. Waldrop, who started the year on the disabled list with a strained elbow, has posted a 1.26 ERA in nine games for Rochester.

"Jeff's been kind of scuffling; I think we've all seen that," Manager Ron Gardenhire said. "All of his pitches are kind of blending together. He's got to get back to slowing the ball down, locating the ball a little bit better, so send him back down to get going. And Waldrop's back healthy, throwing the ball well. We'll see how he does up here."

Span's OK after collision

Denard Span said he hit the back of his head against the center field wall, when he jumped trying to catch A.J. Pierzynski's triple in the seventh inning.

"It's definitely a ball that I would like to get back and try to steal one from A.J.," Span said. "I just mistimed my jump and jumped into the wall."

It was a scary moment for the Twins because of the concussion issues he's had in the past. But when Manager Ron Gardenhire started to head to the outfield, Span waved him off.

Gardenhire let Span finish the inning but took him out before the top of the eighth, with the White Sox leading 10-2.

"Initially I was shaken up, but I didn't want [Gardenhire] to come all the way out there," Span said. "I was fine to finish the inning; I probably could have finished the game, as well. But the score was kind of out of hand, and he told me he was going to put [Darin] Mastroianni in. I told him that was a good idea to relax and kind of take the rest of the day off."

Before the game, Gardenhire said, "I think Span Man might have been our best player in this first half, consistently getting it done." Span is batting .277 with a .341 on-base percentage and understands why everyone gets concerned when he gets shaken up.

"Any time I have a collision or run into the wall," he said, "my reaction is probably the same as you guys: 'Am I OK?"
