Flaherty (soreness) was able to do some throwing Friday, Byron Kerr of MLB.com reports.

EDGE Analysis

Flaherty experienced some general soreness following his last start Aug. 15 against the Padres, 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 O's rotation beyond that has to be determined. Flaherty could perhaps handle Sunday's series finale versus Colorado or Monday's series opener versus the White Sox.
