Flaherty (soreness) was able to do some throwing Friday, Byron Kerr of MLB.com reports.
Flaherty experienced some general soreness following his last start against the Padres Aug. 15, during which he was lit up for seven earned runs on four hits and four walks over just three innings. Kyle Bradish will start for Baltimore on Saturday against the visiting Rockies, but the Orioles' pitching schedule beyond that has to be determined. Flaherty could perhaps be ready to take the hill for Sunday's series finale versus Colorado or Monday's series opener versus the White Sox.
