Andy Murray angered by 'extremely loud' grunting

Listen to Argentina's Carlos Berlocq grunting against Andy Murray in the fourth round of the BNP Paribas Open, which Murray afterwards described as "extremely loud" and "erratic".

The world number three won 7-6 6-4 but complained to the chair umpire about the noise level of his opponent.

Murray will meet Juan Martin Del Potro in the quarter-finals at Indian Wells on Friday.
