Seattle Mariners' Kenji Johjima, right, slides into home plate, trying to score from second base on a single hit to left field, as catcher Ivan Rodriguez takes the throw in the fourth inning.

Curtis Granderson homered for Detroit, which had tied San Francisco for the longest winning streak in the majors this season.

Baek (1-0) struck out four and didn't walk a batter in his first career complete game. He gave up a triple to Carlos Guillen in the second, singles to Brandon Inge in the third and eighth and Craig Monroe in the fifth, and a double to Gary Sheffield in the ninth.

Tigers starter Nate Robertson (3-2) lasted only 4 2-3 innings, despite retiring the first seven batters. He allowed six runs and 10 hits.

With Seattle trailing 2-0, Jose Guillen's homer in fourth gave the Mariners the lead for good after Ibanez and Richie Sexson had singled with one out.

The inning ended when Kenji Johjima was thrown out at the plate by left fielder Craig Monroe on Jose Lopez's single. It appeared that Johjima had beaten catcher Ivan Rodriguez's tag, but he was called out by home plate umpire Dan Iassogna.

The Mariners added three more in the fifth on RBI doubles by Ibanez, Sexson, and Adrian Beltre. Beltre's hit, with two out, knocked Robertson out of the game.

Seattle also got three in the sixth on a run-scoring double by Ichiro Suzuki, an RBI single by Jose Vidro, and an RBI double by Ibanez.

Granderson led off the bottom of the first with his sixth homer of the season, driving Baek's 1-2 pitch into the right-field stands. The Tigers made it 2-0 in the second when Carlos Guillen scored on Sean Casey's sacrifice fly.
