Naomi Osaka suffered a shock second-round exit to Carolina Muchova at the Madrid Open, but there was no such trouble for Simona Halep as she held off Zheng Saisai.

Second seed Osaka was playing just her second match on clay since the 2019 French Open due to injury issues.

She became the latest big name to fall at the hands of Muchova.

The world number 20, who had already defeated two top-five players this season, prevailed 6-4 3-6 6-1 in a time of one hour and 49 minutes in the Spanish capital.

Osaka has now lost two of her last three matches, having been eliminated from the Miami Open quarter-finals by Maria Sakkari at the end of March.

“I think today for me it was quite different from the last time I lost in Miami, and I actually think I played much better here. So, I’m very happy about that,” Osaka said.

“I think what I can take away from this is that I tried my best throughout the entire match. I think, tennis-wise, I felt I was too defensive in the first set.

“I wouldn’t say I’m happy that I lost, but I think I learned a lot. So, that’s all I can hope for.”

Two-time champion Halep has yet to drop a set in this year’s tournament after seeing off unseeded opponent Zheng 6-0 6-4.


Halep took nine games in a row at the start of the match.

But, like in her opening-round win over Sara Sorribes Tormo, she had to hold off a late surge from her opponent to advance.

Next up for Halep is a last-16 showdown with Elise Mertens, who beat Elena Rybakina 7-6 (7-4) 7-5 in the last of Sunday’s matches.

Fifth seed Aryna Sabalenka safely advanced earlier in the day thanks to a 6-3 6-3 win against Daria Kasatkina, while Sakkari beat Anett Kontaveit 6-3 6-1.

Sabalenka was on course to face Victoria Azarenka for a place in the quarter-finals, but the Belarussian withdrew from her match with Jessica Pegula because of a back injury.

Elsewhere, Jennifer Brady, who knocked out fellow American Venus Williams in the first round, eased past Jelena Ostapenko 6-2 6-1.
