Mauer has MRI on injured heel
Mauer had the examination on Tuesday and was out of the lineup against the Detroit Tigers for the fourth straight game. Manager Ron Gardenhire says the test revealed a deep soft tissue bruise. The reigning AL MVP remains day to day.
Wilson Ramos started at catcher again in place of Mauer. Ramos had seven hits in nine at-bats in his first two major league games.
The Twins activated right-hander Nick Blackburn from the family medical leave emergency list to start the game against the Tigers. Blackburn has been tending to a family matter since April 30.
The Twins optioned right-hander Jeff Manship to Triple-A Rochester to make room.
