Wei-Yin Chen blanked the Rays en route to his tenth win of the season, and the Birds evened-up the series with a 4-0 win over Tampa on Saturday night.
Chen (10-6) allowed just five hits and a walk while fanning four over seven shut-out innings. He's the first Oriole to hit double digits in W's this season, and only the second Taiwanese-born player to accomplish the feat.
The Birds finally broke out of their slump, going 5-for-9 with runners in scoring position. All four runs came with two outs.
The O's and Rays are both 56-51 and tied for second place in the East. The two clubs go at it again on Sunday afternoon, with Miguel Gonzalez taking the mound for the Birds.
