India’s Rohan Bopanna and his Australian partner Matthew Ebden entered the men’s doubles quarter finals of the Australian Open with a impressive 7-6, 7-6 victory over Wesley Koolhof of the Netherlands and Croatia’s Nikola Mektic here on Monday.

The 43-year-old Bopanna and Ebden, who are seeded second in the draw, were broken early in both sets but showed themselves to be up to the task with some great returns against the 14th seeds.

The Indo-Australian pair will next meet the sixth-seeded Argentine duo of Maximo Gonzalez and Andres Molteni.

They are also the highest seeded pair remaining in the men’s doubles competition and Monday’s win was a praiseworthy one against the former top-ranked doubles pair in the world.

Bopanna’s service let him down initially as he was broken in the second game of the first set with the 14th seeds racing to a 3-0 lead within first 15 minutes of the start.

However, the veteran Indian, who recently retired from Davis Cup duties, was back in his groove with some signature backhand down the lines and deft overhead lobs which were placed inches inside the baseline.

In the seventh game of the first set, Mektic and Koolhof made some glaring unforced errors, allowing the Indo-Aussie pair to get their foot in the door. There was no looking back for them after that as they held both nerve and serve.

In the second set also, Bopanna lost his first service game with the Dutch-Croat duo going up 4-2 and showing signs of a revival.

The tie-breaker saw Bopanna-Ebden race to a 3-0 lead. They did not slip thereafter.
