MELBOURNE (Reuters): Naomi Osaka ended Serena Williams’ bid for a record-equalling 24th Grand Slam title in a storm of power hitting on Thursday, humbling the American great 6-3 6-4 to reach her second Australian Open final.

In a rematch of their tumultuous 2018 U.S. Open decider, Osaka underlined her status as the new queen of women’s tennis and soaked up the cheers from the Rod Laver Arena crowd as fans returned to the Grand Slam after a five-day lockdown.

Williams, however, was left in tears.

The 39-year-old cut short her post-match news conference after breaking down when asked whether she had just had a bad day at the office.

“I had so many opportunities ... it was just ... I made too many mistakes there and easy mistakes,” said the American. “Not like .... I was on the run or anything. They were just easy, easy mistakes.

“I don’t know. I’m done,” she added before exiting the room in tears.

Osaka, the 2019 champion, will meet the winner of Jennifer Brady and Karolina Muchova for the title as the 23-year-old bids to claim her fourth Grand Slam crown.

“It’s just always an honour to play her and I just didn’t want to go out really dud. I just wanted to try my best,” Osaka said after her 75-minute masterclass on a steamy afternoon.

“I was a little kid watching her play and just to be on the court playing against her is a dream.

“You’re competitive, you are playing against another competitor, that itself is the funnest part because tennis is a game.”

Williams’ record bid ended with another near-miss, having also reached the finals of four other Grand Slams since her last major crown at the Australian Open in 2017.

Williams and Osaka’s last Grand Slam clash was full of drama at Flushing Meadows in the 2018 final, with the American losing her temper at the chair umpire and fans jeering during the trophy ceremony.

Williams had come to Melbourne Park seeking a 24th Grand Slam title but it was her 24th unforced error that ended her campaign.
