Wei-Yin Chen pitched well in a no-decision against the Athletics on Friday, surrendering just two runs on five hits over 6 1/3 innings. Chen struck out four and didn't issue a walk in the ballgame. The only scoring against him came on a pair of solo home runs off the bats of Josh Donaldson and Derek Norris. He left in line for his seventh victory of the season, but the Orioles bullpen was unable to hang on for him. Chen will bring a 4.13 ERA, 1.32 WHIP and 50/11 K/BB ratio into Wednesday's start against the Red Sox.
