McCann is out of the lineup Wednesday against the Mariners, Bob Dutton of the Tacoma News Tribune reports.
EDGE Analysis
McCann received the starting nod behind the dish for the first two games of the series, but manager A.J. Hinch will give the veteran backstop some time off his feet Wednesday. Evan Gattis, who occupied the DH spot in Tuesday's game, will step in to catch Charlie Morton while McCann rests up.
