The Pirates optioned Flores to Triple-A Indianapolis on Saturday, Danny Demilio of PittsburghBaseballNow.com reports.
Flores went 2-for-5 and notched his first MLB home run during his brief run with the Pirates, but he'll head back to Triple-A now that Henry Davis has returned from paternity leave. Flores could return to Pittsburgh later in the season if the big club's catcher depth is tested again, though most of his time will likely be spent in the minors.
