The Twins made the move before Friday's game at Cleveland, where the right-handed Blackburn was originally slated to start. The team said Blackburn is dealing with a personal family matter. He must be on the list for a minimum of three days and a maximum of seven days.
Right-hander Kevin Slowey was moved up to start Friday against the Indians, and Manship will start Saturday.
The right-handed Manship went 2-2 with a 3.48 ERA in four starts for the Red Wings. He pitched briefly for the Twins last season.
