Naomi Osaka survives, Amanda Anisimova cruises

However, the victor of the past two grand slams has no intention of changing. Won the last two, so I kind of want to win this one really bad. If I have to break a person, I feel I have the ability to do that. The gulf between her and 23-time major champion Williams was quickly apparent. During the Australian Open, she invited her mom to fly down. Osaka bucked that trend early in 2019, when she became the first repeat victor since Williams' French Open-Wimbledon double in 2015, by winning the Australian Open. Osaka is now the world no 1 whereas Katerina Siniakova is ranked world no 42.

The three-time Roland Garros champion and 23-time grand slam victor will take on fellow American Sofia Kenin in the next round, with Osaka a potential opponent in the quarter-finals.

Naomi Osaka revealed she "felt like a challenger" during her second-round French Open clash with Victoria Azarenka.

Belarus' world number 43 Victoria Azarenka lost to world number one Naomi Osaka of Japan 6-4, 5-7, 3-6 in the French Open second round, BelTA has learned.

"There is no way that it's going to be a similar match to the one I played her in Rome a year ago", Osaka said.

Two-time Australian Open champion Azarenka has been getting closer to her best form having finally returned full-time to the tour last spring following a bruising custody battle over her toddler son. "I've been through a lot of things in my life".

"I was lucky enough to play her (Azarenka) twice before this and I knew she was playing really well", said Osaka.

The Japanese star, bidding to add the French Open to her U.S. and Australian Open titles, battled back from a set and a break down to defeat Azarenka 4-6, 7-5, 6-3. She also matched a Paris best with the third-round berth.

"That's just great to be achieving stuff similar to her", she added.

Serena Williams' quest for a 24th Grand Slam title ended with her earliest loss at a major tournament in five years.

She was up a set and a break at 5-3 in the second before losing her way.

"I called my mom in like the second round, and I was like, 'Do you wanna come to Australia?"

Across the court though, Osaka was unmoved.

She raced into a 5-1 lead in the decider and, although Azarenka grabbed the next two games, Osaka kept her focus to reach the third round.

She hit 15 unforced errors in the opening set on Lenglen court as Azarenka, 29, dominated to go 5-1 up.

They would play for more than 1½ additional hours, and Azarenka certainly had opportunities to edge even farther ahead, such as when she had a break point to go up 5-2 and serve for the victory but netted a forehand.

Also Thursday, 17-year-olds Amanda Anisimova and Iga Swiatek both romped into the third round with comprehensive victories over seeded players to firmly mark themselves out as future stars.
