Duffy (Achilles) underwent successful surgery Friday, Marc Topkin of the Tampa Bay Times reports.
It sounds like it was a fairly extensive procedure, with Duffy undergoing a bone debridement and having his bursa removed. A recovery timetable was not immediately offered up but the Rays reportedly think Duffy should be ready for spring training. The 25-year-old only played in 21 games with Tampa Bay and 91 games overall, slashing .258/.310/.357. He hit .295/.334/.428 with 12 homers and 12 stolen bases in 2015.
