The Orioles scored three runs in the first inning and that would prove to be plenty as they beat the Red Sox 6-0 on a rainy night in Baltimore.
The Orioles record improved to 33-31 with the win while the Red Sox dropped to 29-36.
Wei-Yin Chen tossed 7.0 innings of four-hit ball with seven strikeouts, becoming the latest opposing pitcher to shut down the Red Sox lineup.
Rubby De La Rosa (5.2 IP, 4 ER) got the start for the Red Sox and quickly ran into trouble in the first. After Nick Markakis was retired, Steve Pearce reached on a walk and Adam Jones plated him with a double. Two batters later, Chris Davis belted a two-run home run to right to make it 3-0.
De La Rosa kept the Orioles quiet after that until the fourth inning, when Nick Hundley slapped one the other way to bring home J.J. Hardy.
After Chen got Ortiz to ground into an inning-ending double play in the top of the seventh, the skies opened up, leading to an hour and 38-minute delay.
Play would eventually resume, as the teams returned for a scoreless seventh. Chris Capuano then took over on the mound in the eighth and gave up two bases loaded walks to make it 6-0.
For the Red Sox, it was another poor offensive performance. During one stretch, they were victims of three straight inning-ending double plays. The Sox leave Baltimore having scored only one run in the series. Thankfully, they were able to escape with a win the other night behind some strong pitching.
Next up for Boston is a four-game series with Cleveland, who swept the Red Sox just a little more than a week ago. Jon Lester will get the ball for the Sox on Thursday as they look to get back on track.
