Aussie ace John Millman wasn't pleased with Jack Sock after their match at BNP Paribas Open Indian Wells and made sure the American knew about it.
He bounced back from a break down in the decider to win through 7-5, 4-6, 6-3 in two hours and 31 minutes on Saturday.
But the drama came at the net where Sock barely acknowledged Millman and the latter approached him with a heated exchange to follow.
