Hamilton (ribs) could return Friday against the Mariners, Jeff Fletcher of the Orange County Register reports. An MRI on Hamilton's abdominal area last weekend revealed rib cage inflammation, resulting in a whopping seven pain-killing injections in his back and chest. Fortunately, the treatment seems to be doing the trick, as Hamilton was able to hit off a tee both Monday and Tuesday. While it's no lock he returns Friday, it does sound like Hamilton will be available in some capacity for the final series of the regular season.
