Interim manager Daren Brown gave designated hitter Russell Branyan another day to give his sore lower back more time to heal; gave catcher Adam Moore the day off completely and put center fielder Franklin Gutierrez in the DH spot.
"With the [scheduled] day off tomorrow, it's important to try and have Branyan ready to go on Tuesday," said Brown, looking ahead to the series opener against the Blue Jays in Toronto.
"Guti has played quite a bit for us and he's had some issues with a couple of different things -- sickness and whatnot. We'll give him a break today and also use the day off to our benefit, especially this late in the season."
Gutierrez went into Sunday's game with five hits in his last 17 at-bats, two doubles, a home run and three RBIs.
Catcher Guillermo Quiroz, promoted from Double-A West Tennessee on Wednesday, made his first start and appearance of the season for the Mariners.
This probably will be a rare treat the rest of the way, watching Moore behind the plate.
"He's been catching a lot," Brown said of Moore, "and we expect him to catch a lot from here on out."
