Joe Mauer (back) is not in the Twins' starting lineup on Monday.

Joe Mauer had to leave the Twins' game early on Sunday due to back spasms and it was an issue that he said flared up during batting practice. This is not a surprise that the Twins will rest Mauer and take every precaution to make sure the face of their franchise gets back to 100%. This injury isn't expected to be a major issue moving forward.ANALYST: Drew Phelps
