Jessica Pegula

The world No. 44 brought the same Australian Open energy and intensity with her to the Qatar Open in Doha. Pegula posted a seamless 6-3, 6-1 scoreline against China's Wang Qiang to advance into the 500-level event's round of 16. The American qualifier has claimed eight of her last nine matches and will face Jelena Ostapenko, who upset Kiki Bertens, 6-0, 6-2, next.

In her first match since Roland Garros opening loss in September, the American dazzled her way past Adelaide finalist Belinda Bencic, 6-4, 6-1, to reach the second round in Doha. The world No. 19 will have an opportunity to avenge her US Open loss to Maria Sakkari next.

Andrey Rublev

In his first 10 matches of the season, Rublev has been on fire, only falling to countryman Daniil Medvedev in the Australian Open's quarterfinal. Rublev easily moved past qualifier Marcos Giron, 7-6 (1), 6-3, to set up a clash with three-time major champion Andy Murray.

"We will see, it's going to be interesting. I mean he's Andy, he's a legend. He beat me once almost, 6-0, 6-0, 6-0," Rublev said following his opening win in Rotterdam.

Ons Jabeur

The world No. 31 has bounced back since falling in straight sets at the Australian Open to eventual champion Naomi Osaka. Jabeur put on an impressive performance to defeat Anna Blinkova, 6-2, 6-2, in Doha. She will next face No. 2 seed Karolina Pliskova. The round of 16 affair will be a re-match of their three-set battle on the same courts just a year ago. Jabeur came out on top in that edition and will be looking to do the same on Wednesday.
