The Pirates optioned Bidois to Triple-A Indianapolis on Wednesday.
After making just three outings for Pittsburgh since being called up on June 13, Bidois will head back to Indianapolis. The 25-year-old most recently appeared Monday, allowing three earned runs on four hits and a walk while striking out two in just two-thirds of an inning against Philadelphia. The Pirates will replace Bidois with Cam Sanders on the 26-man roster.
