PARIS -- Australian Ashleigh Barty claimed her first Grand Slam singles title Saturday, June 8, with a 6-1, 6-3 win against unseeded Czech teen Marketa Vondrousova in the French Open final in Paris.

Barty, the highest-seeded player remaining at No. 8, has now beaten Vondrousova, 19, in each of their three meetings.

With the victory, Barty will move up to No. 2 in the world rankings when they are updated this week. She's the first Australian woman to climb that high since Evonne Goolagong Cawley did it in 1976.

"It's unbelievable ... I played the perfect match today," said Barty. "I am so proud of myself and my team. It has been a crazy two weeks."

Vondrousova was playing in her first Grand Slam final, the first teenager to advance that far at a major since 2009 and the first at Roland Garros since 2007.

It was Vondrousova's third final and third runner-up finish this season. She's a tour-best 27-6 since the Australian Open.

"I was nervous," admitted Barty. "Marketa's had an amazing season, she's just starting her climb. She's going to be in many more Grand Slam finals."

Barty stormed ahead in the opening set, winning the first four games before stumbling and allowing Vondrousova a break. But Barty quickly recovered to put the set away.

After suffering a break to open the second set, Vondrousova picked up some momentum and managed to hold on her next three service games.

But Vondrousova was unable to crack Barty's serve and, trailing 5-3, was broken once again to seal the match. The two sets were the only ones she lost at Roland Garros.

"Even though I didn't get the win today, I really enjoyed my time and I'm really happy with everything that happened here," Vondrousova said.

Barty now has two titles this season in three finals. She also won the Miami Open and finished runner-up in Sydney.

Nadal unbeatable?

Beating Rafael Nadal on clay is the ultimate challenge, but that may have already become mission impossible for his opponent Dominic Thiem, even before Sunday's French Open final gets underway.

Seeking a record-extending 12th title at Roland Garros, where he has an intimidating 92-2 record since 2005, Nadal has had the ideal preparation for Sunday's showdown, beating arch-rival Roger Federer in straight sets on Friday before enjoying a rest day.

Austrian fourth seed Thiem, his victim in last year's final, has enjoyed none of those advantages, needing two weather-disrupted days and five sets to get rid of world number one Novak Djokovic in the other semi-final.

Thiem, who has become part of the Roland Garros furniture with his fourth last-four appearance in a row, risks being mentally drained when he steps onto Court Philippe Chatrier, Nadal's back-lawn.

"The physical part is one thing, and the mental part is another thing," his coach Nicolas Massu told reporters after his protege's semi-final spanned 24 hours.

Men's doubles

Kevin Krawietz and Andreas Mies of Germany claimed their first Grand Slam title when they beat France's Fabrice Martin and Jeremy Chardy 6-2 7-6(3) in the doubles final on Saturday.

The German pair, who beat 16-time major champions Mike and Bob Bryan en route to the final, raced through the opening set with two early breaks.

The French duo, who defeated top seeds Lukasz Kubot and Marcelo Melo on their way to the Court Philippe Chatrier showdown, regained their composure in the second set but their opponents remained rock solid at the net.

The unseeded Germans simultaneously fell on their backs after sealing the result on their first match point.
