Naomi Osaka joked that she did not want to face Bianca Andreescu ever again after the Japanese was forced to fight from a set down to reach the China Open semi-finals on Friday.

In a captivating first meeting between two of the brightest young talents in tennis, the 21-year-old Japanese squeezed through 5-7, 6-3, 6-4 in over two hours in Beijing.

Osaka plays title-holder Caroline Wozniacki on Saturday in the last four.

The first instalment in what should be the start of a long rivalry did not disappoint as Osaka brought the teenage Canadian’s run of 17 wins in a row to an end.

“Listen, I don’t want to play her any more, I’m good, one-and-done,” former No 1 Osaka joked of the prospect of more thrilling matches in future against the 19-year-old Andreescu.

Turning more serious, the two-time Grand Slam winner Osaka said that she felt she had been “counted out” after hitting poor form following her Australian Open triumph in January.

“I’m still here,” Osaka, the world No 4, said, adding that Andreescu’s recent stunning success, including winning the US Open final against Serena Williams, had driven her on.

Andreescu, whose ascent has been so fast that she did not even play in Beijing a year ago, said she was relishing facing Osaka more in future.

The duo exchanged warm words at the net at the end.

The Canadian, ranked sixth in the world, revealed: “I said, ‘Congrats, you played amazing.’

“She said, ‘You’re amazing.’ I said, ‘We’re going to have so many more matches like this. I can’t wait to see what the future holds.’”

In the other semi-final on Saturday, world No 1 Ashleigh Barty of Australia plays Kiki Bertens of the Netherlands.

Progress pleases Murray

Andy Murray said that his comeback from career-saving hip surgery was progressing better than expected despite going down fighting in the quarter-finals.

The 32-year-old Briton lost 6-2, 7-6 (7/3) to top seed Dominic Thiem, but said: “I think this (week) was maybe the best in terms of how I played since I came back.

“It was great for me, I played three matches in four days, which is quite a lot.

“Actually I felt better than I expected today, as well,” said the former No 1, who had a major operation in January and only returned to singles tennis in August.

Asked by AFP if he was further ahead than he expected to be in his comeback, he replied: “Yeah, maybe.

“I’m getting there, this week is better than last week, I hope next week is better than this week,” the three-time Grand Slam champion said. “That’s how I have to try to keep going to see where my limit is, I don’t think I’m at that limit now.”

The 26-year-old Austrian Thiem plays Karen Khachanov of Russia in the last four.

Third seed Stefanos Tsitsipas of Greece will play second seed Alexander Zverev in the other semi-final.

Germany’s Zverev, at 22 a year older than Tsitsipas, has cruised into the last four, yet to drop a set all week.
