Petra Kvitova has made it through to the quarter finals of the Australian Open with a battling victory over Anna Ivanovic.

The number 2 seed took just under an hour and a half to win 6-2, 7-6 against the former world number 1. Kvitova came into the tournament with the Wimbledon crown already secured earlier in the year, and would love to take a second grand slam title, though there are many contenders capable of this feat in this year’s tournament.

Although the first set was won with relative ease, as Kvitova broke her opponent in the third and seventh games, the second set saw the game come alive, with Ivanovic showing that she is coming ever closer to regaining the form that gave her such success in the past.

It was the Czech player whose serve was first tested in the second set, and Ivanovic couldn’t take two break points in the second game. Instead, Petra held her serve and then edged ahead in the fifth game with another break of serve. However, the Serbian raised her game, and put the pressure right back on by breaking back in the tenth game when Kvitova just needed to win her serve for the match. The tie break saw the number 2 seed take control of the game again, and it finished 7-2 to give Kvitova her two-set victory and a place in the quarter finals.

“It was a tough match, especially at the end,” said Kvitova after the match, “I lost eight points in a row but I was happy with how I played in the tie-break.”

Her win sets up a meeting with the unseeded Italina Sara Ennari in the quarters, who beat Zheng Zie in straight sets in the last round, losing just 3 games in the encounter. Despite this, the tie will be seen as an easy draw for Kvitova, (shes odds-on according to the latest online tennis bettingodds) and she should be able to book herself a place in the semis without too much trouble.
