Fast National ratings for Wednesday, June 10, 2015.

"MasterChef" delivered Wednesday's biggest audience among young viewers as FOX won the key demo, while repeats of "Criminal Minds" and "CSI: Cyber" helped CBS triumph overall. 

Also winning its hour overall for CBS was "The Briefcase," but the much reviled summer reality series slipped again in total viewers (but remained flat in the key demo).

Wednesday night was low on notables, so let's get straight to the numbers...
