CLEVELAND -- Taijuan Walker pitched six innings without allowing an earned run and Norichika Aoki's two-run triple provided all of the offense as the Seattle Mariners beat the Cleveland Indians 2-1 Wednesday night at Progressive Field.

Aoki's two-out, two-run triple in the second inning was the big hit in the game while Walker and three relievers combined on a four-hitter. Walker (1-0) pitched six innings, allowing one unearned run on three hits, with six strikeouts and no walks as he continued his mastery over Cleveland.

In three career starts vs. the Indians Walker is 3-0 with a 0.45 ERA. In 20 innings he has allowed one earned run on 13 hits, with 20 strikeouts and two walks.

The loss went to Danny Salazar (2-1) who was almost as stingy as Walker. Salazar pitched seven innings, giving up two runs on three hits, with seven strikeouts and three walks. Salazar and two relievers combined on a three-hitter. Cleveland pitchers held Seattle hitless and scoreless over the last seven innings.

The Indians missed a great scoring opportunity in the eighth inning when Tyler Naquin led off with a single against Joaquin Benoit. But Jose Ramirez, trying to sacrifice, bunted into a force out at second, retiring Naquin. Ramirez then moved to second on a wild pitch, but Benoit retired the next two batters to end the inning.

Steve Cishek pitched the ninth to pick up his second save.

Seattle took a 2-0 lead in the second against Salazar.

Adam Lind led off the inning with a single to left field and went to second when Chris Iannetta walked. Salazar retired Leonys Martin on a flyout to center and Luis Sardinas struck out for the second out, but Aoki ripped a triple into the right-field corner, scoring Lind and Iannetta.

Cleveland got a run back in the bottom of the third.

With Naquin at first and one out, Ramirez hit a sharp grounder that handcuffed Lind at first base and skipped past him into right field. Ramirez made it to second on the two-base error and Naquin advanced to third. Naquin then scored on a sacrifice fly by Jason Kipnis, cutting the Seattle lead to 2-1.
