Murray dropped the next three points to lose the game, and then brought up the call again with Cicak at the ensuing changeover, saying something similar had happened earlier and play had continued.
“Exactly the same thing,” Murray said. ''And I told you.''
He also spoke to a tournament supervisor about it, pleading his case and saying, “That's not fair.”
Murray would lose the next seven games, including the final five games of the fourth set. He would lose 7-5 in the fifth and deciding set.
U.S. Open officials later released a statement saying the sound was from a digital audio sound processor that malfunctioned.
