Kristina Mladenovic could be No. 1

Kristina Mladenovic has two Grand Slam women’s doubles titles, two mixed doubles titles, has won the year-end championships and has made six other major Slam finals.

But she’s never been No. 1. 

Her career high is No. 2, reached in Oct. 2016.

That could change, as the 26-year-old Frenchwoman will top the rankings on Monday – unless Elise Mertens wins the French Open women’s doubles title with partner Aryna Sabalenka.

Mertens and Sabalenka play Lyudmyla Kichenok and Jelena Ostapenko Thursday in a rain-delayed quarterfinal.

If they win, they would battle Babos and Mladenovic in Friday’s semifinal for that top spot.

No. 1 ranking in play in Stuttgart

As the top seeds roll into action at the WTA Premier tournament in Stuttgart, Germany this week, the No. 1 ranking is once again in play – barely.

The WTA Insider reports that Petra Kvitova, ranked No. 3 and 322 points behind No. 1 Naomi Osaka, must win the title.

But if Osaka wins her first match, on Thursday against frequent nemesis Hsieh Su-Wei, she will remain No. 1 regardless.

World No. 2 Simona Halep, just 185 points behind Osaka but with a quarter-final to defend, pulled out with a hip injury after Romania’s unsuccessful bid to reach the Fed Cup final last weekend.
