Johanna Konta, Garbine Muguruza, Petra Kvitova all advance in Doha

Johanna Konta, Garbine Muguruza and Petra Kvitova all completed straight sets wins in the Qatar Open on Tuesday.

British No 1 Konta avenged her shock Australian Open loss at the hands Bernarda Pera as she beat the American qualifier 7-6 (7-5), 6-1 in one hour and 28 minutes.

Pera had the initial upper hand as she broke in the 11th game, but the world No 11 hit back and then took the tie-breaker before securing the second sets without any problems.

“I‘m very happy to have come through that,” Konta was quoted as saying by Reuters.

“I knew going into the match that it was going to be tough…

“Even if I wasn’t going to get through the match with a win, I still wanted to make sure that I did more and just did a little bit better than last time.”

Two-time Grand Slam winner Muguruza claimed a 6-3, 6-4 over Duan Yingying from China, but she didn’t have it all her own way and only wrapped up the victory on her eighth match point.

“It was a very tough match,” the Spaniard said.

“It doesn’t matter how many match points I had, but I won. That’s the important part, and I‘m so happy because it’s been so long since I’ve competed. It’s good to have a victory.”

Kvitova set up a clash with Agnieszka Radwanska as she was way too good for wildcard Cagla Buyukakcay, claiming a 6-0, 6-3 victory.

Meanwhile, Madison Keys beat Qiang Wang of China 6-1, 6-4, Kristina Mladenovic claimed a 6-2, 6-4 win over Shuai Peng and Sam Stosur was a 6-4, 6-2 winner over Irina-Camelia Begu.

World No 1 Caroline Wozniacki and second-ranked Simona Halep will be in action on Wednesday.
