Simona Halep reclaimed second place in the WTA rankings on Monday after her run to the Qatar Open final, while Doha champion Elise Mertens climbed back into the top 20.
Halep moved up a spot as Australian Open runner-up Petra Kvitova dropped two places to fourth, with Sloane Stephens matching her career-best of third despite not playing since losing in the last 16 in Melbourne.
Naomi Osaka remains top of the standings, while Serena Williams returned to the top 10 for the first time since July 2017.
Mertens rose to 16th after the Belgian rallied from a set down to beat Halep 3-6, 6-4, 6-3 on Sunday to claim the biggest title of her career.
In the men’s side, Stan Wawrinka returned to the world’s top 50 on Monday for the first time since last year’s French Open after his run to the final in Rotterdam.
The three-time Grand Slam champion is on the road back to his best after serious knee injuries and reached his first final last week since losing to Rafael Nadal at Roland Garros in 2017.
The 33-year-old Swiss was beaten in three sets by Gael Monfils, though, with the Frenchman climbing 10 spots to 23rd.
Wawrinka sits 41st in the rankings after a rise of 27 places.
