Joe Nathan isn't sure if the Twins want him to pitch for them next season. The right-hander said he hasn't heard "one way or the other" about a contract extension. Nathan, 36, is in the final season of a $47 million, four-year contract. "I understand both sides of it," Nathan said. "It doesn't concern me. The only thing I really can do is keep going out and performing, showing them that I'm healthy, that I'm getting stronger. From there, I think, things will fall in place."
