(SportsNetwork.com) - Chris Young tries to win his fourth consecutive decision on Tuesday when the Seattle Mariners continue a four-game series with the Minnesota Twins at Safeco Field.

Young was terrific again on Wednesday in Houston, as he held the Astros to a pair of runs and two hits over seven innings. He also struck out eight batters and improved to 8-4 to go along with a 3.11 ERA.

"It's the health," Young said of his first-half success. "Being out there and taking the ball every fifth day and helping this club. Going out there and giving innings and giving the team a chance to win. That was my goal coming in and I feel like my track record in terms of performance has always been decent. And if I stay out there and healthy, I've always performed relatively well. So I'm confident in who I am, what I do, what I have to do to be successful and I feel blessed to have a clean bill of health at this point."

The 35-year-old righty is 3-0 with a 1.44 ERA over his last four starts and his .206 opponents' against batting average for the season is fourth best in the AL. He has also been impressive at home, where he is 5-1 with a 2.19 ERA in eight starts this season.

Seattle improved to an MLB-best 15-6 over its last 21 games on Monday, as Hisashi Iwakuma continued his historic dominance over Minnesota, tossing seven scoreless innings to help the Mariners to a 2-0 win.

"Threw the ball extremely well ... pretty impressive outing from him," Mariners manager Lloyd McClendon said of Iwakuma.

Iwakuma (7-4) was stellar, limiting the Twins to just four hits while striking out a season-high 10 batters. In 33 2/3 career innings against Minnesota, the 33-year-old has yielded just two unearned runs.

"He doesn't really throw the same thing every time, his ball moves all over the place," Twins manager Ron Gardenhire said. "The guy's got great stuff."

Only former Cub Jeff Pico has a longer stretch without giving up an earned run against a single opponent since 1914. He owns the record with 35 innings against Atlanta.

Danny Farquhar and Fernando Rodney both struck out two in perfect innings of relief. Rodney picked up his American League-best 26th save of the season.

Mike Zunino opened the scoring with a solo home run in the bottom of the second inning against Twins starter Kevin Correia (4-11), who surrendered both runs on five hits over seven innings to absorb the tough-luck loss.

Correia matched San Diego's Eric Stults for most losses in the majors with his 11th of the season.

Getting the call for Minnesota on Tuesday will be right-hander Phil Hughes, who was roughed up by his former team, the New York Yankees, his last time out. Hughes gave up seven runs and eight hits in 6 1/3 innings of that one, as he fell to 8-5 to go along with a 3.95 ERA.

"I felt good early," Hughes said. "I felt like my stuff and my command was miles ahead of my last two starts. I can take that away from it."

Hughes has faced the Mariners 11 times (8 starts) and is 5-3 against them with a 3.67 ERA.

The Twins took two of three games from the Mariners at Target Field when the clubs met from May 16-18.
