Rays' Matt Duffy: Feels good after running bases

Duffy (heel) ran the bases Monday and will do so again Wednesday, Marc Topkin of the Tampa Bay Times reports.

Monday marked Duffy's first time running the bases since he underwent heel surgery last fall, and he reported feeling good the following day. The Rays figure to remain cautious throughout Duffy's rehab and they may be hesitant to offer up a timetable, but Duffy thinks he could begin a rehab assignment next week and return to the major-league club by late May. He is expected to play shortstop upon activation.
