Duffy (Achilles) felt the best he has felt during his rehab process while doing drills at the team's spring training complex Tuesday, CSN Bay Area's Alex Pavlovic reports.
It is unclear when Duffy will be ready to go on a rehab assignment, but it certainly sounds like he is making progress, so a late-July/early-August return seems possible. Meanwhile the Giants will try to cobble together production from Ruben Tejada and Conor Gillaspie at the hot corner until Duffy returns.
