The pumping of fists and chest butting returned as Leander Paes [ Images ] and Mahesh Bhupathi [ Images ] beat Roger Federer [ Images ] and Yves Allegro in the men's doubles second round at the Olympic Games [ Images ] in Athens on Tuesday.

The 'Indian Express', seeded fifth, beat the Swiss pair 6-2, 7-6 (9-7) to make it to the last eight stage, where they run into the fourth-seeded Zimbabwean duo of Wayne Black and Kevin Ullyett, who got the better of Andre Sa [ Images ] and Flavio Saretta of Brazil [ Images ] 6-3, 6-4 in the their second round match.

The Indians effected breaks in the third and seventh games on Allegro's service to take the first set rather easily.

The second set was a thriller with both teams giving little away. Games went with serve and as a result the set petered out into the tie-breaker, which the Indians won 9-7.

In fact, Paes and Bhupathi, cheered by some members of the Indian contingent including Anjali Bhagwat and Suma Shirur, were forced to save two break-points in the second game on Federer's serve.

The Swiss led for the first time in the match when they went up 2-1 and maintained the lead till the 12th game.

Serving to stay in the set, Paes's serve came under pressure at 15-40 but the former world number one doubles pair held their nerve to hold serve and take the set into the tie-breaker.

In the tie-breaker, the Indians were 1-3 down but successfully attacked Allegro's serve to level at 3-3.

They forged ahead at 6-4 on Bhupathi's serve and held two match-points but Bhupathi committed his first double fault to fritter it away the advantage.

But at 8-7 Bhupathi produced a strunning service return to clinch the set and match.

For Federer, it was a bad day as he also lost in the men's singles, going down to unheralded Czech Tomas Berdych in the second round.
