Two-time Wimbledon champion Petra Kvitova battled windy conditions to book her place in the quarter-finals of the Qatar Open with a three-set win over Jelena Ostapenko.

The 29 year-old saw off the 2017 French Open winner 6-2 5-7 6-1 in exactly two hours in Doha.

After a slow start saw Ostapenko claim an early break to lead 2-0, Kvitova switched into gear and began playing some scintillating tennis, winning six games in a row to take the opening set.

The second set was a more topsy-turvy affair as the pair shared four breaks in a row between them before the Latvian showed the better stamina as she broke Kvitova twice more to send the match to a decider.

But it appeared Ostapenko had put everything into the second set and left the tank empty at the start of the third, with Kvitova racing into an ultimately decisive 5-0 lead and closing out the match with ease.

After the match, Kvitova said: “There’s no chance to have tactics in this wind. I lost to her in our last match, so I knew what to expect.

"The wind changes everything. It’s difficult to put the serve in and she returned the second serve well. It was difficult from the first point. I needed to be more patient, for sure. It’s about taking time. It’s really difficult.”

The Czech star will now face either No 3 seed Karolina Pliskova or Tunisian Ons Jabeur for a place in the last four in Qatar.
