Duffy (Achilles) will be activated by the Rays on Friday, the Tampa Bay Times reports.
Duffy completed his final rehab game for Triple-A Durham on Wednesday, and after going 5-for-17 at the plate over a five-game rehab stint, the team determined the infielder is ready to join them at the big league level. During that rehab assignment, Duffy played all five games at shortstop, the spot he'll presumably take over upon his return to the majors. The Rays have a team day off Thursday, but Duffy should be on the roster by the time they open a three-game set against the Yankees on Friday.
