Yasmani Grandal will be reinstated Tuesday from a 50-game suspension for a positive testosterone test.

The suspension called into question his numbers as a rookie catcher with the Padres.

Beyond saying he made a "mistake," Grandal has never told team officials why he took PEDs.

Grandal was part of San Diego's second-half resurgence in 2012, hitting .297 with eight home runs and 36 RBIs in 60 games.
