Murray overcomes Del Potro in Paris

World No 1 Andy Murray is through to the last 16 at Roland Garros after defeating Juan Martin del Potro in straight sets.

The Scot narrowly edged two tight opening sets before running away with it in the third for a 7-6 (10-8), 7-5, 6-0 victory in 84 minutes.

Murray was not in the greatest form heading into this week, but appears to be approaching something like his best at just the right time. After two so-so performances in the first two rounds, his third-round victory over the dangerous Del Potro was his best showing yet.

Del Potro actually started the stronger of the two, breaking early for a 4-2 lead that had his opponent on the back foot.

But Murray kept fighting and after nearly breaking back in game eight, he did find the opening at 4-5, finally clinching his sixth break point of the match after saving a Del Potro set point.

Having forced the tie-break, Murray narrowly edged it by four mini-breaks to three to go one set up, with Del Potro's anguish at having let his advantage slip clearly visible. 

A break right at the top of the second set put Murray further in control, and though Del Potro would get back on level terms several games later, the Argentine was not able to consolidate his position, allowing Murray to break back in the very next game and serve out the set.

Now finding himself two sets down, Del Potro's challenge totally faltered in the third as he appeared to struggling with a worsening groin injury. 

Murray broke three times to race through the set in quick time and set up a fourth-round clash with American John Isner or Russia's Karen Khachanov.

"Whoever won that first set had big momentum," the Scot said afterwards. "It's slow and heavy and coming back in these conditions is difficult.

"I thought I played some good tennis towards the end and I expected a tough match.

"It was tough. I think he was playing much better than me in the first set. Both of us hand some chances in the first set, the second set was the same. Both those sets could have gone either way."

Joining Murray in the fourth round was third seed Stan Wawrinka, who dispatched Italian Fabio Fognini 7-6 (7-2), 6-0, 6-2 in just under two hours.
