Garbine Muguruza bounced back from her loss in the Qatar Open final with a win over Irina-Camelia Begu in the first round at the Dubai Championships on Monday, as Madison Keys and Elise Mertens also progressed.

Muguruza was playing two days after a straight-sets loss to Petra Kvitova in the Qatar final.

“It was tough because I arrived yesterday, so it was just fighting spirit,” Muguruza said. “Just trying to adapt as fast I can.”

Her second-round opponent is Amanda Anisimova after the U.S. player beat Ana Konjuh 6-2, 6-2.

It was Anisimova's return to the court after she hurt her ankle in a fall and withdrew from the Qatar Open.

Keys beat Liang En-Shuo 6-1, 6-1 and held serve throughout. It was only Keys' third match this year after she missed the Australian Open following a positive test for the coronavirus. Keys faces Anastasia Potapova in the second round.
