Twins catcher Joe Mauer is focused on being more durable heading into the 2011 season. He is coming off a number of nagging injuries suffered last season and minor surgery in December to alleviate some swelling in his left knee. Mauer has also advised closer Joe Nathan, who had elbow surgery last year, to take it slow. "My advice to Nathan, I'm taking that to heart, too," Mauer said, looking ahead to his own spring plan. "I should be ready to go when we report. Just got to be smart about it and get ready for the season."
