Seattle is four games behind Oakland in the AL West and 2 1/2 behind Boston in the wild-card race. The Mariners have six games left, including three against the A’s at Safeco Field next weekend.
Moyer has been Seattle’s most reliable starter, going 19-7 with a 3.42 ERA this season.
The 40-year-old left-hander pitched eight strong innings in the Mariners’ 5-1 win over Texas on Wednesday. He allowed one run and four hits while striking out five and walking two in becoming the fourth AL pitcher to win at least 19 games this season.
“He’s a guy who’s been through the wars,” Seattle manager Bob Melvin said of Moyer.
Melvin hopes Moyer gives him a better effort than Gil Meche did on Sunday. Oakland hammered Meche for five runs in one inning as Seattle lost 12-0.
The Mariners had 31 hits in the first two games of the weekend series, but managed only four against Oakland starter Ted Lilly and three relievers Sunday.
The Mariners have put their playoff chances in serious jeopardy by losing five of their last eight games.
“This is obviously a big game, a big opportunity,” Seattle catcher Dan Wilson said after Sunday’s loss. “It’s a completely different race if we win today, completely different. Put it this way, this loss takes it out of our hands if (the A’s) win three.”
The Angels have won just three of their last 12.
Garret Anderson was out of the lineup for the second straight game Sunday because of lower back spasms as Anaheim picked up an 11-6 win over Texas.
Anderson hadn’t missed a game until being a late scratch from the lineup on Saturday. He has a career-high 196 hits, and six games left for a chance to get 200.
