Orioles manager Buck Showalter said Thursday that Wei-Yin Chen has been "a little slow" to recover from surgery to remove bone spurs in his right knee. Chen had the procedure back in October. Although Showalter said the left-hander's rehab hasn't been "seamless," he doesn't expect the slow recovery to affect Chen's status for Opening Day. It's unclear at this point if Chen will be on a normal schedule in spring training.
