Vargas is not in the lineup Tuesday against the Diamondbacks, Rhett Bollinger of MLB.com reports. Vargas was hit by a pitch in the fourth inning of Monday's game, but stayed in and there's been nothing to suggest his absence Tuesday is related. Rather, it seems manager Ron Gardenhire just thinks the 24-year-old could use a mental break, following a 1-for-11 showing in his previous three starts. Trevor Plouffe will serve as the designated hitter as Eduardo Nunez steps in at the hot corner.
