The Marlins reinstated Diaz from the 7-day injured list Tuesday.
The details behind Diaz's absence were never disclosed, but the infielder now rejoins the Marlins. His brief IL stint may have come at a good time, as Diaz went 2-for-28 in his last 11 games before being sidelined. He fills the active roster spot of Brian Anderson (shoulder), whom the Marlins placed on the 10-day IL on Tuesday. Jon Berti will get the nod at the hot corner Tuesday, though Diaz could appear off the bench against the Phillies.
