New York, Sep 9 - India's Leander Paes and Lukas Dlouhy of the Czech Republic upset top seeds American brothers Bob and Mike 6-4, 3-6, 7-6(8) to storm into the finals of men's doubles in the US Open tennis tournament here Wednesday.

Fourth seeds Paes and Dlouhy, who had lost to the Bryans' in the semi-final here last year, held their nerves in the tense decider to pull off the thriller in an hour and 51 minutes.

The deciding set itself lasted 55 minutes with Paes and Dlouhy wasting a match point in the 10th game off left-hander Bob's serve.

The Indo-Czech pair raced to a 5-0 lead in the tie-breaker, before Bob and Mike fought back. The Americans then saved four match points at 6-2 to draw level. Finally Paes and Dlouhy wrapped it up in their next match point with Paes showing great reflexes at the net and putting away a volley.

Paes and Dlouhy will meet the winner of the other semi-final between India's Mahesh Bhupathi and Mark Knowles of Bahamas and Andy Ram of Israel and Max Mirnyi of Belarus.
