The Twins could have catcher Joe Mauer in the lineup as early as Tuesday, according to the Associated Press. Mauer has yet to play this season because of time spent on the disabled list with a sore lower back. He played in two rehabilitation games at Class-A Fort Myers over the weekend. "He feels really great right now," said Minnesota manager Ron Gardenhire, who spoke with Mauer on Saturday. A decision on his return will be made on Monday, according to the team.
