Daria Saville's major admission about husband at French Open

Daria Saville has admitted to being distracted by her husband's match at the French Open on Wednesday before her stunning win over grand slam champion Petra Kvitova.

Saville scored one of the wins of her career when she upset the two-time Wimbledon champion 6-4 6-2 at Roland Garros to advance to the third round.

But even while preparing for the landmark victory, an anxious Saville has revealed she was getting distracted by news of her other half Luke.

Luke Saville, playing alongside Aussie compatriot Jordan Thompson, won his first round doubles match 7-6 (6) 7-5 over Dušan Lajović and Jiří Veselý.

"I was watching the lives scores from Luke's match," Dasha told AAP.

"And I was thinking, it's either going to be a really good day for us or a really bad one!"

After Luke's victory, he rushed over to Court 7 to watch his wife enjoy the best win yet in her stirring resurgence, supporting her in his own understated way.

Daria and Luke have very different schedules on the WTA and ATP tours, so it's not often they get to support each other at the same tournament.

'Dasha' sounded as if she actually quite enjoyed seeing Luke at courtside, urging her on to her surprisingly dominant victory over Kvitova.

"He's not someone who's going to be super loud, so it's OK," she smiled.

On Friday (local time), the Melbourne couple will both be in action again, as Dasha takes centre stage in an attempt to reach the last-16 of a grand slam for the first time in five years since making the fourth round of the Australian Open in 2017.

She faces Martina Trevisan, an Italian friend she's known since they were youngsters at a training camp in Livorno and played in an under-14s event.

"Oh my god, the funniest thing," Saville said.

"I beat her there in 2008 - epic match, I won in three and the home crowd wasn't happy.

"I think it's gonna be the same - long rallies, lots of screaming and 'forzas, vamoses, allezs, come ons!'"

Saville and Trevisna never met at the professional level but practised happily together recently, with Saville still blissfully unaware at that stage that they were due to play each other in the third round.

Saville, set to break back into the top 100 after the win over Kvitova, is predicting another "epic" against Trevisan, who recently won her maiden WTA title in Morocco to shoot to a career-high ranking of 59.

This time last year, Dasha still slowly recovering from Achilles tendon surgery back in Melbourne after falling out of the top 600 in the world, while Luke was globetrotting on the doubles circuit.

They barely had the chance to see each other last year before their wedding in December, but playing together in the mixed doubles at the Australian Open helped launch Dasha's return to the big-time.

They had been hoped to play mixed doubles too at Roland Garros as well, didn't make the cut.

"Well, he did serve for it twice in that match in Australia - and we lost," Dasha said.
