O'Flaherty (shoulder) could return from the DL as soon as Tuesday's series opener against the Tigers, Susan Slusser of the San Francisco Chronicle reports. O'Flaherty made rehab appearances with High-A Stockton and Triple-A Nashville over the past week, tossing two scoreless innings. It doesn't appear he's suffered any negative effects as a result of those outings, so he'll likely be quickly plugged back in as one of manager Bob Melvin's top lefty arms out of the bullpen.
