Plouffe (ribs) took grounders during batting practice before Saturday's game, Brandon Warne of ColdOmahaMN reports.
Plouffe showed continued progress from a cracked rib by taking groundballs with Miguel Sano and Danny Santana before the game. He'll begin a rehab assignment Monday, and after several minor league tuneups, he figures to return to the Twins sometime in the first week of August.
