Orioles third baseman Manny Machado has hit just .217/.269/.304 in 23 at-bats against left-handers this season.
Machado struggled against southpaws in 2014 as well, posting a .642 OPS against lefties and a .802 OPS against righties, but the split has been more pronouced this season, as the third baseman has powered to a .288/.366/.519 line while hitting all six of his home runs against righties.
Machado is set to face Mariners righty Taijuan Walker on Tuesday but then has a pair of matchups against left-handers on Wednesday and Thursday.
