Orioles left-hander Wei-Yin Chen (knee) announced Saturday that he expects to be ready for Opening Day. The 28-year-old southpaw progressed slowly in his recovery from surgery to remove bone spurs in his right knee, but says he's fine and appears to be on track now. He's been fairly consistent in his first two seasons stateside, and represents a nice late-round option as a sixth or seventh starter in mixed league drafts.
