David Nalbandian to rival John Isner in quarter-finals of 2011 Heineken Open

PanARMENIAN.Net - Former World No. 3 David Nalbandian of Argentina will rival Heineken Open defending champion John Isner (U.S.) in quarter-finals of the 2011 Heineken Open.

Nalbandian earned an easy straight sets victory over the German Philipp Petzschner to reach the quarter-finals of the 2011 Heineken Open, an ATP World Tour 250 Event, being played in Auckland, New Zealand.

Nalbandian finished off the match with a 6-3 6-2 scoreline.

It took less than an hour for the Argentine to subdue the German. Nalbandian earned the break in the second-game of the first set and maintained that lead till the end to wrap it up with a 6-3 score, tennisearth.com reported.

While John Isner beat Haase 3-6 7-6 7-5 in a match that lasted two and a quarter hours and so badly did he play in the first set that it looked as if the tournament's third seed was highly likely to be knocked out in his first match. However, the world No 19 was able to pull the win out of the bag by snatching the victory in his only break point of the match. Afterwards Isner admitted that he'd had a shocker, stuff.co.nz reported.

Nalbandian and Isner rivalled only once earlier, with the Argentinean celebrating victory in the match.
