Iwakuma, Mariners shut out Tigers
SEATTLE -- Mariners right-hander Hisashi Iwakuma outdueled Detroit rookie Michael Fulmer to lead Seattle to a 3-0 win over the Tigers on Monday night.
Iwakuma (13-7) threw seven scoreless innings, allowing just five hits, before new Mariners reliever Arquimedes Caminero and rookie closer Edwin Diaz finished off the win.
Diaz, who replaced Steve Cishek as closer last week, now has five saves in as many chances as Seattle (58-53) won for the sixth time in seven games.
Fulmer (9-3) took his first loss since June 17 despite giving up just two runs on five hits over seven innings. He had won seven of eight decisions dating back to May 10.
Detroit (61-51) dropped its second game in a row to fall 2 1/2 games behind the Cleveland Indians in the American League Central standings.
Kyle Seager, Mike Zunino and Guillermo Heredia each had an RBI single for the Mariners, who took a 2-0 lead in the second inning and added a run on Heredia's single in the eighth.
The only Detroit baserunner to get past first base was Ian Kinsler, who led off the game with a walk and moved to second on a one-out single from Miguel Cabrera but ended up stranded there.
The Tigers, who had not been shut out since July 8, have scored just one run over their past two games.
Nelson Cruz went 2-for-3 with a double and a run scored for the Mariners.
Diaz, a 22-year-old rookie who began this season as a Double-A starter, retired all three batters in the ninth inning. He has a 1.80 ERA over 29 appearances since getting called up on June 4.
Caminero was making his Mariners debut after getting traded from Pittsburgh over the weekend.
The Mariners jumped out to a 2-0 lead on RBI singles from Seager and Zunino in the second inning.
Seager followed Cruz's leadoff double with a single up the middle, giving Seattle a 1-0 lead. After a one-out walk, Seager scored on Zunino's single to left.
