World number four Brooks Koepka, who trails by three, expressed his distaste for wearing a mic during play. Koepka: “I don't understand why they want us to wear a mic when there is a boom mic 10-feet away from every shot that I hit. If the announcers just shut up and listen you could hear every word that we're talking about. So I don't understand what the thing is. Half the time the lady is holding a boom mic and she's listening to everything that we're saying all the way down. So if they would just shut up they could hear everything."
