"As we kept throwing, it became clear that it was getting harder and harder to play catch," Nathan said. "It became clear that it didn't feel great. This was going to be an easy answer for me to know I wouldn't be able to pitch without getting this thing taken care of."Although the news of surgery is not what Nathan had hoped for, he said there had been plenty of time for him to come to terms with the idea over these past two weeks. Sunday morning's game of catch has given him a bit of closure in the fact that he now knows what he needs to do. "The worst-case scenario would be if there was a grey area and I wasn't sure where I was at," Nathan said. "It would be if I tried to battle through this for some time and then it ended up not going well. Get it done and [have] plenty of time to be back. "I don't fear whether I [can] come back next year. The biggest disappointment is the obvious -- just missing this year." Nathan was asked if he planned to rehab from the surgery in Minnesota. He said that would be his preference, but only if he and the team determine that it will be the best spot for his recovery. "I think it will help me get through this thing and at least be a part of the team a little bit," he said. "I'm very comfortable in Minnesota. We have a house there, and my family would like it. Obviously, I would like to help out whoever is thrown into that [vacant closer's] role." With Nathan now officially out for the 2010 season, the Twins have two weeks before Opening Day on April 5 to either trade for a closer or choose one from their current pitching staff. Among the pitchers who have been considered to be in-house options are Jon Rauch, Matt Guerrier, Francisco Liriano, Jose Mijares and Jesse Crain. "It's a tough loss because Nathan is your closer, and normally your bullpen is as good as that guy at the end," Twins manager Ron Gardenhire said. "Now, we have to find somebody to step in there and do a job. Not replace him, but do a good job for us and get some outs. Whether it's one guy or two guys, we'll find out. We're going to decide here as we go along. ... We've gone through injuries before and you have to find people to step up. That's what we're going to try to do here."
