Sweet Chen music (O's win 2-1)

For Wei-Yin Chen, the song remained the same while facing the Seattle Mariners. Last week, Chen tossed eight scoreless innings at Safeco Field, leading manager Buck Showalter to tweak the rotation and pair them again tonight. It worked. Chen went 7 1/3 innings tonight, holding the Mariners to one run and five hits. He walked one, the final batter he faced, and struck out a season-high eight. Andrew Miller replaced Chen in his Orioles debut. He got Dustin Ackley to ground into a force and walked Robinson Cano after Ackley stole second and advanced to third on catcher Caleb Joseph's throwing error. Kendrys Morales bounced into a force to strand both runners. Chen left to a rousing ovation after throwing 104 pitches, the same reception that greeted Miller as he warmed up. All four infielders stood near the mound and watched him. In Chen's last four starts, he's walked three batters and struck out 21. Is that good? In his last two starts, he's held the Mariners to one run and 10 hits over 15 1/3 innings, with two walks and 11 strikeouts. Also good, right? Chen hadn't completed six innings in his two previous starts before dominating at Safeco Field. The Orioles have played six consecutive one-run games. They lead 2-1 tonight as we head to the bottom of the eighth. Tonight's attendance: 39,487 Update: Game over.
