Twins catcher Joe Mauer says he's made a lot of progress in terms of regaining strength, but he's not yet ready to return to the field. Mauer said he's added the 15 pounds he lost when he was sick and that the strength is returning to his legs. He took some swings off soft tosses and worked out on the field before Tuesday's game against Detroit, and manager Ron Gardenhire said the goal is for Mauer to take full batting practice with the team this week. He hasn't tested his legs yet, however, by crouching or catching any pitches. "You've got to get back into baseball shape, things like that. I've still got some work to do, and I wish I knew when I would be back," Mauer said. "I know everybody else out there wishes, too, but I've just got to keep going in the right direction."
