Naomi Osaka applauding

Naomi Osaka got her revenge over Kristina Mladenovic as she kicked off the defence of her Indian Wells title with a solid win, but fellow seeds Petra Kvitova and Caroline Wozniacki crashed out.

World No 1 Osaka was stunned by Mlandenovic in Dubai in February, but she got the better of the Frenchwoman in the second round of the BNP Paribas Open, securing a 6-3, 6-4 victory.

“I’ve never been a defending champion before so I was pretty nervous and I’m glad I got the win,” the two-time Grand Slam winner said.

Venus Williams rolled back the years as she beat third seed Kvitova 4-6, 7-5, 6-4.

“She has been playing so well and you never know what’s going to come off her racket,” former world No 1 Williams said after the win.

“I was just happy to have your energy to get pumped up. I just love the battle.”

Former world No 1 and 13th seed Wozniacki also crashed out as she was upset 7-5, 2-6, 7-5 by Russian Ekaterina Alexandrova, who will face Belinda Bencic in the third round after the Swiss beat Alison van Uytvanck 6-4, 6-1.

Fifth seed Karolina Pliskova beat Misaki Doi 6-7 (4-7), 6-1, 6-1, eighth seed Angelique Kerber advanced with a 6-0, 6-2 win over Yulia Putintseva while ninth seed Aryna Sabalenka was a 6-3, 4-6, 6-0 winner over Ajla Tomljanovic.
