SEATTLE — Hisashi Iwakuma wouldn't let the Minnesota Twins or his team's defense prevent him from earning his 10th win of the season.
The Seattle right-hander allowed four hits in six shutout innings, and the Mariners scored six runs in the second en route to an 8-2 rout on Thursday night.
The Mariners also matched their season high with three errors along with two more fumbles that were ruled hits. But Iwakuma picked up the defense each time and worked out of jams.
"Stuff like that happens in a game in a long season," the Japanese-born Iwakuma said through an interpreter. "You have to see how much you can cover up as a pitcher. That's what I have in mind."
Iwakuma (10-4), who won his third straight decision, struck out nine and walked one. Since moving into the starting rotation on July 2, 2012, Iwakuma has gone 18-8 with a 2.78 ERA in 38 starts.
"I was not real pleased with out infield play," said Mariners acting manager Robby Thompson, a former infielder. "But (Iwakuma) battled and he got himself out of it. The infield and outfield pick up the pitchers at times — well, he picked up the infield tonight.
"He threw more pitches than what he should have but he battled and got us out of a couple jams that we put him into."
Against the Twins, Iwakuma is 4-0 and hasn't allowed an earned run in 26 2-3 consecutive innings over his four starts — Minnesota's third longest streak. He has held the Twins to a .168 batting average with eight walks and 24 strikeouts.
