Wei-Yin Chen was brilliant over eight scoreless innings to lead the Baltimore Orioles to a 3-0 win over the Oakland Athletics in the second test of a four-game set at The Coliseum.
Chen (2-2) scattered two hits and two walks while striking out five to earn his second straight win. Jim Johnson then stranded a runner in the ninth to pick up his AL-leading ninth save. He is now tied with Pittsburgh closer Jason Grilli for the most saves in the majors.
"(Chen) only had two or three three-ball counts all night. He had good command of his fastball all night on both sides of the plate. He was the difference maker," Baltimore manager Buck Showalter said.
Steve Pearce, Nate McLouth and Nick Markakis each drove in a run for the Orioles, winners in seven of their last nine games.
Oakland starter Tommy Milone (3-2) allowed just one unearned run over 6 2/3 innings to absorb the loss. He allowed six hits and struck out five in his second setback in as many starts.
"I have high expectations for myself. Outings like this are what I'm looking for every time out," Milone said.
The O's broke a scoreless tie in the seventh as Pearce drove home J.J. Hardy with a base hit up the middle. Hardy opened the frame with a single to right. Oakland right fielder Josh Reddick bobbled the ball and Hardy took second before coming around on Pearce's base hit.
Baltimore added two more in the ninth inning. With the bases loaded, McLouth, in a pinch-hitting role, ripped a grounder to second baseman Jed Lowrie, who couldn't handle the sharply hit ball and Hardy scored from third. Markakis added a sacrifice fly to left to score Chris Dickerson.
Baltimore went just 1-for-10 with runners in scoring position ... Oakland, which leads the majors in runs, was shut out for the third time this season ... The A's are just 4-9 since winning nine straight games earlier this season.
