Iga Swiatek marked her 23rd birthday with a straight-sets victory over Marie Bouzkova at the French Open on Friday, maintaining her charge for a third successive Roland-Garros title.

Swiatek was pushed all the way by Naomi Osaka in her second-round match on Wednesday, but she enjoyed a far more serene outing on Court Philippe-Chatrier in the third round.

The world number one raced to a 6-4 6-2 win as Bouzkova struggled to match her heavy-hitting, and she could even afford to surrender one of her two breaks at the tail end of the opener.

Swiatek broke immediately at the start of the second set, setting the tone for a powerful finish to the match, her victory fittingly sealed with a thumping forehand up the line.

She will face Anastasia Potapova next up after the Russian overcame Wang Xinyu in three sets on Friday.

Data Debrief: Perfect celebration for Swiatek

Since the WTA rankings were first published in 1975, only two world number ones have won a match at Roland Garros on their birthday, Justine Henin in 2007 and Swiatek on Friday.

She is also the only player this century to reach the fourth round of the women's draw on each of her first six French Open appearances. 

Naomi Osaka comprehensively dispatched Greet Minnen on Tuesday to make a winning start to her Madrid Open campaign and earn a first win on clay for two years.

Japanese star Osaka triumphed 6-4 6-1 in only 79 minutes, swiftly booking a second-round clash against Liudmila Samsonova.

Osaka reached the last 32 at the WTA 1000 events on the hard courts of Indian Wells and Miami but had lost to Martina Trevisan at the first hurdle in the Open de Rouen on clay at WTA 250 level last week.

This was therefore a welcome return to form against Belgian qualifier Minnen and represented her first triumph on the surface since beating Anastasia Potapova at this tournament in 2022.

After an even start to the contest, the first set was level at 4-4. But Osaka then assumed full control, winning eight of nine games to race to victory.

Data Debrief: Osaka dominates on serve

Osaka was not broken at all in the match and allowed Minnen only one break-point opportunity across the whole contest.

She fired down eight aces to only three double faults, and won 13 of her 16 first-serve points in the second set.
