The sixth-seeded combination beat the American twins, Bob and Mike, 6-3, 5-7, 7-6 (7/5) to make it to the last four, where they will face the eighth-seeded Israeli duo of Jonathan Erlich and Andy Ram.

Erlich and Ram defeated Frenchmen Marc Gicquel and Fabrice Santoro 6-4, 6-1 in their quarter-final clash.

Bhupathi and Knowles needed two hours and 24 minutes to overcome the top seeds. They could have won in less time as they had vital leads in all three sets before the Bryans came back strongly. The third set itself was 56 minutes long.

The sixth seeds did not commit a single unforced error in the match and capitalised on three of the six break points they got.

They won 73 per cent of the points on their first serve and won a total of 112 points compared to 107 by the Bryans.

Bhupathi is also in the mixed doubles draw partnering Sania Mirza [Images] and will take on the eighth seeds Nathalie Dechy of France [Images] and Andy Ram in the semi-final.
