Duffy (hamstring) took groundballs and ran in the outfield at 60 percent speed without issue prior to Saturday night's game against the Twins, Bill Chastain of MLB.com reports.
The injured shortstop remains hopeful of coming off the disabled list when he's first eligible, which would be this coming Friday. Manager Kevin Cash confirmed that Duffy will not be with the team when it begins a nine-game road trip following Sunday's series finale versus the Twins, but the Rays' skipper remarked that he hopes to see Duffy "at some point on the trip."
