Verdasco stuns in-form Zverev in two-stage win

"If I'm speeding and you don't catch me ... you've got no proof", Kyrgios said before resuming his battle with Kohlschreiber.

If the seedings hold, del Potro and Murray will meet in the third round, a mouthwatering prospect given their two tussles in 2016 were classics.

"You know, to just hear a guy in the back of the court just give me some positive things to think about - I get pretty internal at times, and when he's telling me to focus on things, I kind of just think tactically".

Scans have cleared Kyrgios of any major structural damage to his hip and, unlike before the Australian Open when he was battling a knee injury, he's not required to take cortisone. I don't feel like my level is a problem.

"I thought he was really laid back, he just gave me a couple tips every now and then".

Kyrgios took early control when Kohlschreiber gunned a forehand long to lead 4-2 before sealing the first set in 30 minutes.

Top-seeded Andy Murray is safely through to the second round of the French Open after beating Andrey Kuznetsov of Russian Federation 6-4, 4-6, 6-2, 6-0.

John Isner hit 31 aces and, more surprisingly, converted all three of his break points in a 6-3, 4-6, 7-6 (5), 6-3 victory over Jordan Thompson of Australia to reach the second round at the French Open.

Not that the red dirt is the only surface tennis players have complained about. His mere presence is an acknowledgment that Kyrgios, a bull by nature who has been fined for on-court outbursts and suspended for an unsporting lack of effort, knows he needs to navigate through the china shop without breaking quite so many dishes.

The death of Del Potro's grandfather, which prompted his withdrawal at Estoril, left him short of practice on dirt courts, but a run to the Rome quarter-finals suggests the 2009 US Open champion could get amongst the frontrunners over the coming fortnight. There is no regrets.

"I enjoyed it very much", said Wawrinka, who won at Roland Garros in 2015.

The Spaniard, who has won six of his seven career titles on clay, broke Zverev twice to clinch the third set before the German collapsed in the fourth.

"I think you can get rid of it. I will do all the right things after this ... and hopefully it keeps pulling up okay for me to play".

"The world doesn't stop now".
