The Padres reinstated Fermin (head) from the injured list Friday.
Fermin has been on the shelf since July 3 with a head bruise but began playing in rehab games July 8 and has since gone 3-for-12 with a walk and two RBI in three contests. Now fully healthy, he'll return to the active roster for the start of the second half but will remain on the bench Friday while Luis Campusano starts behind the plate. Rodolfo Duran was optioned to Triple-A in a corresponding move.
