Duffy (heel) took ground balls and participated in batting practice Friday, Marc Topkin of Tampa Bay Times reports.

Duffy was going to be re-evaluated Friday, and although the results of the examination aren't known as of now, this is a promising step for the embattled infielder. There's still no firm date for Duffy to resume his rehab assignment, but that should come forth as he continues to ramp up activities.
