SEATTLE -- Newly promoted catcher Chris Herrmann, who made his Mariners debut on Sunday, is expected to be placed on the 10-day disabled list with a sore rib cage prior to Wednesday's game against the Rangers.
David Freitas, who was optioned to Triple-A Tacoma when Herrmann arrived on Sunday, was back with the team Wednesday and will take his roster spot if a DL stint is required.
Herrmann felt an issue in his side during batting practice Tuesday and had an MRI test on Wednesday.
