The typically slugging AL West champion A's (35-23), who will host a best-of-three wild-card series starting Tuesday at the Coliseum, are still struggling as an offense but doing just enough. They won 3-1 in 10 innings Friday night on Mark Canha's two-run homer.

Khris Davis hit a sacrifice fly in the fourth inning, but that was it for the A's, whose hitting is hardly where they would hope with the playoffs coming.

Liam Hendriks (3-1) pitched a perfect seventh before finding trouble in the eighth, when Ty France also singled home an insurance run for Seattle.

Seattle was the home team for Game 2, a makeup from a Sept. 3 postponement following a positive coronavirus test result by A’s right-hander Daniel Mengden on Aug. 29 in Houston.
