FORT MYERS, Fla. -- Twins closer Glen Perkins has been held out of action after suffering from cramping in his side on Friday, but he is expected to resume throwing in a side session on Monday, manager Paul Molitor said Sunday.
Perkins, who last pitched in the exhibition against the University of Minnesota on Wednesday, suffered the injury while playing catch on Friday. But he went through pitchers' fielding practice drills without any issues on Sunday, and he is scheduled to play catch again on Monday, which means he could return sometime next week if all goes well.
"Whether it was a cramp or a little tug, whatever it was, thankfully he's feeling better," Molitor said. "I saw him participate in PFP today, and he did fine. But I'm not sure when he'll throw off the mound again. But everyone is thinking it's not as bad as originally feared."
Molitor said the injury isn't serious, but the Twins are just being cautious with Perkins, who was an All-Star each of the last two seasons.
"He told me he might've had a bad belt on," Molitor said with a laugh. "The good thing is the next day he said he was fine and that he didn't even know what it was. But we are not going to ignore the fact he thought he felt something. So we'll take it slow."
