The Twins will be without starting catcher Joe Mauer for at least two weeks after an MRI revealed a strain in his left quad muscle and the team placed him on the 15-day disabled list. Mauer has been battling a sore quad for nearly the entire first month of the season, but he only felt the increased pain and stiffness in his leg on Friday night while running the bases in a game against the Red Sox. He came to the park on Saturday and took batting practice before having to pull himself out of the lineup. And after seeing the results of Mauer's MRI on Sunday morning, the Twins made the decision that it was most important to give the catcher time to let the injury heal.
