Twins catcher Joe Mauer reported to spring training on Sunday without a contract extension in place.

He hasn't talked specifics about a potential deal all winter and he doesn't plan to change that now.

"I'm not going to get into that," the reigning AL MVP said. "It would just open up a can of worms."

Mauer is entering the final year of his deal and Minnesota is trying to get a long-term extension done before the regular season begins.
