Mauer not playing for Twins against Royals
The Twins put Drew Butera at catcher for the game Wednesday night. Mauer's back tightened up before batting practice Tuesday and he was scratched.
While he was criticized for missing too many games last season, Mauer has been one of the Twins' most durable players this year. He has played in 131 of a possible 142 games entering Wednesday, splitting his time among catcher, DH and first base.
