Bryan Woo pitched five scoreless innings as the Seattle Mariners defeated the visiting Oakland Athletics 2-0 on Friday night.
Mitch Garver and Cal Raleigh homered for the Mariners (83-77), who were eliminated from the American League's wild-card race a day earlier when they had a bye.
The A's (69-91) are wrapping up the regular season on the road after playing their final game at the Coliseum on Thursday afternoon. The franchise is expected to play the next three seasons in Sacramento, Calif., while their new ballpark in Las Vegas is being built.
Woo (9-3) allowed just three hits. The right-hander walked one and struck out eight.
The only hits Woo gave up were a two-out single by Zack Gelof in the second, a leadoff single by JJ Bleday in the fourth and a one-out single by Seth Brown in the same inning.
Woo got out of the jam by striking out Gelof and getting Jacob Wilson to ground out to second baseman Leo Rivas.
Seattle's Gabe Speier, Gregory Santos, Tayler Saucedo and Troy Taylor each pitched a scoreless inning of relief, combining for six strikeouts, to complete the shutout.
Taylor allowed a leadoff double to Tyler Soderstrom in the ninth and the runner took third on a wild pitch, but Taylor responded by striking out Daz Cameron and Gelof and getting Wilson to ground out to earn his first major league save.
Oakland left-hander JP Sears (11-13) took the loss despite finishing with a quality start. Sears gave up two runs on four hits over six innings, with three walks and four strikeouts.
The Mariners took the lead when Garver led off the bottom of the second inning by hammering a 1-2 four-seam fastball from Sears over the wall in center field.
Seattle doubled its advantage with one out in the third. Raleigh, serving as the designated hitter, launched a first-pitch changeup deep to left-center. It was Raleigh's team-leading 32nd homer of the season and gave him 97 RBIs.
