Hello and welcome to live updates of the French Open round four clash between world number two, Andy Murray and towering American, John Isner.

GAME, SET AND MATCH! - MURRAY 7-6 6-4 6-3 ISNER. A sixth quarter final berth at the French Open for Murray as he seals a straight sets victory in two hours and 40 minutes.

It played a big role at the end of the second as the pressure got to Isner. It could well do it again in the third if Muzza keeps playing at this level.
