Young pitched six shutout innings and was gone by the time the Oakland Athletics beat the Mariners 3-0.
Yoenis Cespedes hit a two-run homer in the eighth off Charlie Furbush (0-1). Josh Donaldson homered in the ninth off Lucas Luetge.
Young made his first start since Sept. 9, 2012, while with the New York Mets. Troubled by shoulder problems all last season, he went to spring camp this year with the Washington Nationals, was released and signed during the last week of training camp by Seattle.
“I was really, really pleased with his outing,” Mariners manager Lloyd McClendon said. “He got a lot of flyball outs, teased them up in the zone a bit. I think he is close. I saw his breaking ball coming today. When that pitch comes for him, he’s going to be pretty tough.”
“I’m excited for him and I know he is feeling good about his performance,” he said.
The Mariners started the season without Taijuan Walker (shoulder) and Hisashi Iwakuma (finger ligament). Both could be back before the end of the month. Then James Paxson was put on the disabled list last Wednesday with strained lat muscle.
“The results were decent. I gave the team a chance but I feel I can pitch better,” the 6-foot-10 Young said.
“I feel I can throw the ball better. The three walks were too many. Ultimately, I competed, made pitches when I had to. For the first start, it’s not bad but I want to build on it.”
Young has been sidelined with shoulder ailments throughout his 10-year career. Last summer it was so bad he couldn’t even play catch.
“The Nationals’ doctors got me to the right place. They said, ‘We don’t think it’s a shoulder issue. We think it is a nerve issue and it might have been a nerve issue all along,’” Young said. “So I had surgery and since then no pain in my shoulder. It’s been great.”
“Since that point I’ve dedicated myself to getting back to the big leagues and being a successful pitcher.”
A’s starter Scott Kazmir pitched two-hit ball for six innings, striking out nine without a walk. He left with tightness in his left triceps and said it wouldn’t cost him a start.
Dan Otero (2-0) retired two batters in the seventh. Luke Gregerson worked the eighth and Sean Doolittle allowed one hit in the ninth for his first save.
