SEATTLE (AP) — Rookie Gary Sanchez kept up his torrid stretch with his seventh home run in the past nine games, and Masahiro Tanaka won his fourth straight start, leading the New York Yankees to a 5-0 win over the Seattle Mariners on Wednesday.

Tanaka (11-4) threw seven shutout innings and got the better of the Mariners and his former Japan League teammate Hisashi Iwakuma (14-9).

The Yankees won their third straight road series. They took two of three from the Mariners, one of the teams they're chasing in the AL wild-card race.

Sanchez homered into the second deck in left field in the first inning on the first pitch from Iwakuma, his ninth home run in 18 games since joining the Yankees lineup on Aug. 3.

Sanchez added a double later in the game and his intentional walk in the seventh inning led to Mark Teixeira's RBI single for a 4-0 lead. The Mariners took no chances with the new catcher the next time, either, again intentionally walking him.
