The Pirates reinstated Flores (concussion) from the injured list Saturday, Colin Beazley of the Pittsburgh Post-Gazette reports.
After suffering a concussion last weekend, Flores is now fully recovered and will claim the roster spot vacated by Ryan O'Hearn (quad), who landed on the 10-day injured list Saturday. Flores has gone 4-for-15 with a homer, two RBI and two runs scored in the majors this year and will provide depth at catcher and first base.
