Twins catcher Joe Mauer is denying reports that he has set a deadline for an extension with the team. A report by Yahoo! Sports on Monday quoted a source close to Mauer as saying that he would end contract negotiations with Minnesota if a deal wasn't struck by Spring Training. "I'm not going to react to every story/rumor that comes out or comment on any negotiations," Mauer said in a text message of MLB.com. "As far as that report, I don't know where that came from."
