Duffy (achilles) will not return until after the All-Star break in mid-July, Andrew Baggarly of the San Jose Mercury News reports.
Duffy left Sunday's game with an achilles injury that will leave him out until July 15 at the earliest. He is currently in a walking boot and it will take him around three weeks plus a rehab assignment before he is back on the field with the Giants. Duffy is hitting .253 with four home runs and 21 RBI during his 70 games with the club this season.
