Kerber survives Sabalenka surge to reach Indian Wells quarterfinals

On the women's side, world No. 1 and defending champion Naomi Osaka crashed out after she was defeated by Switzerland's Belinda Bencic in a night session on the same court, the 23rd seed claiming a 6-3, 6-1 victory to reach the quarterfinals.

Bencic, ranked 23rd in the world, defeated Osaka 6-3, 6-1 to reach the quarter-finals of the prestigious WTA premier mandatory event, where Osaka won her first tour title a year ago. Winning the remarkable titles of Grand Slam at US Open and Australian Open has driven her lead to become number one in the world.

It was a first win over a top-five player for the 19 year old, who is ranked 61st in the world.

"I'm so happy to be through and so happy with my play".

"I think it's always a bit tricky whenever you change someone in the team, but I feel like for a first tournament we did really well", she said of her partnership with Jenkins, a former United States collegiate star who served as a hitting partner to Venus Williams from 2015 until the end of last season. But I feel pretty good right now, because I tried my best and I don't really have any regrets.

The world No. 23 player will next battle against fifth seed player Karolina Pliskova for her place in the semi-finals.

Osaka's first-serve percentage was 66 and she won 70 per cent of her first-serve points.

It was a tough day for seeded players at the BNP Paribas Open, with Novak Djokovic and Naomi Osaka, the world's top-ranked players, ushered out in the desert. She won everything in the past couple of months. "I haven't played that much, so I wanted to make it count". "It wasn't as easy as the result is saying and I didn't expect it like that, so definitely happy". "It was a little bit more windy in the second set, but I think tactic-wise, I played very solid". I really enjoy that and that's what I work for.

World number two Simona Halep of Romania is also out, beaten 6-2 3-6 6-2 by Czech teenager Marketa Vondrousova.

Halep, who received treatment for blisters on her foot during the match, hit just six winners and piled up 36 unforced errors. "But it's everything I could do today".

Recalling her loss to Bencic at last year's Hopman Cup, the Japanese, who is seeking her first title defence, said: "That's really fantastic, the fact that she was able to come back from her injury and still play at a really top level".

Vondrousova, who beat 2018 runner-up Daria Kasatkina and former French Open victor Jelena Ostapenko on the way to the fourth round, will go for another big win when she faces sixth-seeded Elina Svitolina, who battled to a 7-6 (10/8), 5-7, 6-4 victory over Australian Ashleigh Barty.
