When the Orioles signed left-hander Wei-Yin Chen, 10 days into 2012, they did so because they believed the 27-year-old had displayed unflappability in big games.
He represented his native Taiwan in the Olympics four years ago. He overcame all the obstacles of pitching in a different country, shining for four seasons in Japan with the Chunichi Dragons.
When Chen won his 12th game of the season Aug. 19 in Detroit, he became the first Orioles' pitcher to record that many wins since 2007. But Chen struggled down the stretch, losing his last four decisions heading into the postseason. As his inning count rose, doubt that he has hit the rookie wall grew.
The big stage was never an issue with Chen. But rest proved to be the perfect resolution.
Working on six days rest for just the fifth time this season, Chen held the New York Yankees to two runs (one unearned) on eight hits over 6 1/3 innings Monday night as the Orioles won Game 2 of the American League Division Series, 3-2. It was the Orioles' first home playoff win since Oct. 8, 1997 in Game 1 against the Cleveland Indians.
