Top seed Andy Murray sailed into the fourth round of the French Open with a straight-sets victory over old foe Juan Martin del Potro on Saturday.

Murray fought back to win a thrilling first set on Court Philippe Chatrier and never looked back, triumphing 7-6 (10-8) 7-5 6-0 to move into the last 16.

The world number one beat the Argentinian in an epic Olympic final last year before Del Potro won a marathon Davis Cup five-setter, but Murray produced his best match of the tournament to get the job done in emphatic fashion.

Murray mixed his game up expertly, enjoying success with cute drop shots and making a tiring Del Potro run far more than he wanted to on a gloomy day in Paris to set up a meeting with John Isner or Karen Khachanov.
