28th seed Andrea Petkovic has reached the quarterfinals of a Grand Slam for the fourth time in her career. This is the first time the German has reached this stage of a Grand Slam since returning from injury. Petkovic came back from a set down to defeat qualifier Kiki Bertens 1-6 6-2 7-5.
Kiki Bertens came out swinging freely, dominating her opponent in the opening set. It was in the third game that Bertens made her first move, breaking Petkovic to love. In the next game Bertens consolidated the break, successfully implementing a drop shot on two occasions. Bertens would break once again for a 4-1 lead, again using the drop shot and forcing an error from Petkovic. The set quickly slipped away from Petkovic who was becoming increasingly frustrated, Bertens taking the opening set 6-1. Bertens hit 10 winners to just 4 unforced errors, a commanding opening set from the qualifier.
The second set was a completely different story, Petkovic raising her game whilst Bertens began to hit far too many unforced errors. Petkovic would get herself back on track in the opening game of the set, breaking with a crosscourt forehand winner. Petkovic quickly took a commanding 5-1 lead in the second set. There was some late resistance from the qualifier but it was all too late, Petkovic levelling the match at one set all. Bertens hit a whopping 20 unforced errors in the second set, 5 times more than she hit in the opening set.
The third set was a tight battle all the way to end. It was Andrea Petkovic who obtained the first significant lead. Petkovic broke in the fifth game before consolidating the break with a service hold in the sixth game to take a 4-2 lead. At this point Petkovic had only hit 1 winner for the set so the match was still on the racquet of Bertens. Bertens began to hit freely again, winning three straight games to close to within one game of the quarterfinals. Having not served all that convincingly throughout the match the pressure was on Petkovic to hold to stay in the match. The German stood tall, a solid service hold saw the set levelled at 5-5. Nerves seemed to get the better of Bertens at this point, a double fault and some loose errors handing Petkovic the break and a chance to serve for the match. Petkovic was up to the task, finishing the match off with forehand winner down the line on her second match point.
Petkovic's experience seemed to drag her across the line in the end. The Germans reaction after the match showed just how much this win means to her, reaching the quarterfinals of a grand slam for the first time since her injury layoff. The German could go even further with a winnable math to come.
