Hamilton (shoulder) is expected to open the season on the DL, Alden Gonzalez of MLB.com reports. Surgery to repair the AC joint in Hamilton's right shoulder is set for Wednesday, with a full recovery estimated at 6-to-8 weeks. While that timetable would seem to leave a sliver of hope for Opening Day, GM Jerry Dipoto said that is "probably a little aggressive." After missing nearly all of spring training, Hamilton will likely need a minor league rehab assignment before potentially returning later on in April.
