Aryna Sabalenka is through to the round of 32 at the Madrid Open after beating Sorana Cirstea 6-4 6-3 on Thursday.

It was an ominous start for Cirstea, being broken to love in the opening game, but she stuck with second seed Sabalenka and broke back, before ultimately being pipped to the first set by the impressive Belarusian.

The key was on break points, with Sabalenka claiming all five that she won against the Cirstea serve, while saving six of eight on her own as she ultimately eased to victory.

Sabalenka now has 26 wins on clay in the WTA since 2021, with only Ons Jabeur (37), Iga Swiatek (34), Paula Badosa (31) and Coco Gauff (28) having more during this time.

Gauff also advanced after a routine 6-4 6-1 win over Irene Burillo Escorihuela, making the sixth seed in Madrid the first player to win 35 WTA-1000 main draw matches as a teenager since 2009.

Ninth seed Maria Sakkari defeated Arantxa Rus 6-4 6-4 and fifth seed Caroline Garcia also had few problems against Yulia Putintseva, winning 6-3 6-4.

However, it was not a good day for 10th seed Petra Kvitova, who was beaten 7-6 (11-9) 6-1 by Jule Niemeier, while 13th seed Beatriz Haddad Maia also lost, 7-6 (8-6) 6-3 to Mirra Andreeva and 20th seed Donna Vekic was eliminated in straight-sets by Rebeka Masarova.

Jelena Ostapenko took just 61 minutes to get past Linda Fruhvirtova 6-0 6-3, and will face 14th seed Liudmila Samsonova next, who did not take much longer to see off Maryna Zanevska 6-2 6-3.

There were also wins for Elise Mertens, Badosa, Camila Osorio, Shelby Rogers, Mayar Sherif, Magda Linette and Irina-Camelia Begu.
