Paris, France, 26 May 2016 | tennis.com.au

Australia’s top-ranked male and female players Nick Kyrgios and Sam Stosur have waltzed into the French Open third round but wildcard Jordan Thompson suffered a heartbreaking exit in his Roland Garros debut.

Kyrgios was ruthlessly efficient against a hopelessly outclassed world No.123 Igor Sijsling on Wednesday, winning 6-3 6-2 6-1.

Stosur, too, advanced with relative ease – breaking her Chinese doubles partner Shuai Zhang five times in her 78-minute 6-3 6-4 victory.

Stosur will next face 11th seed and last year’s runner-up Lucie Safarova on Friday.

Kyrgios finished with a ripping backhand – one of 35 winners from his racquet.

He also won five breaks of serve and closed out the match in 70 minutes – faster even than Rafael Nadal’s 80-minute demolition of Australian Sam Groth on Tuesday.

“You don’t really see too many of those matches go that quick, but I thought he was really aggressive from the get-go,” Kyrgios said.

“Every forehand he had he was trying to really pull the trigger. I didn’t feel he felt comfortable extending the rallies.

“I thought there was going to be a lot more rallies today (but) I served well and I returned well. I just played good tactical tennis.”

The 17th seed will next face French nemesis Richard Gasquet, after he enjoyed a breezy straight-sets win over American Bjorn Fratangelo.

Thompson, meanwhile, was outlasted in a five-set epic by the 37-year-old 27th seed Ivo Karlovic of Croatia 6-7(2) 6-3 7-6(3) 6-7(4) 12-10 in four hours and 31 minutes.

He was seeking to become just the second Australian wildcard to reach the French Open third round, following in the footsteps of Thanasi Kokkinakis last year.

But he fell in cruel fashion as Karlovic sent down a tournament-high 41 aces.

Thompson incredibly saved triple break point in the 15th game of the fifth set to hold serve – where a break would have allowed Karlovic to serve for the match.

It proved to no avail, however, as Karlovic eventually broke him with a deep backhand winner in the 21st game and all Thompson could do was stare at the sky before Karlovic sent down three aces to serve out the match.

Bernard Tomic plays his second-round match against Borna Coric on Thursday (Thursday night AEST).
