Joe Mauer is headed back to the Minnesota Twins this weekend. The Twins said Thursday that they plan to activate their catcher from the 15-day disabled list before Friday's game against the Washington Nationals. Mauer, last year's AL batting champion, missed 29 games because of a strained left quadriceps muscle. He was hitting .353 when the injury occurred. Mauer played in a simulated game with minor leaguers on Tuesday and went 0-for-3 with a walk on Wednesday in a Florida State League game with Class-A Fort Myers, catching the whole game until being removed for a pinch runner in the ninth.
