Leander Paes continued his winning run to advance to the mixed doubles' semifinals but it was curtains for Mahesh Bhupathi at the US Open.
Paes, already through to the men's doubles quarterfinals with partner Czech Lukas Dlouhy, teamed up with Zimbabwean Cara Black in the mixed doubles competition.
The fifth-seeded duo defeated the Czech pair of Martin Damm and Vladimira Uhlirova 7-5, 6-2. Paes and Black will now take on the Swedish-Russian team of Jonas Bjorkman and Nadia Petrova in the last-four stage.
Bhupathi, who was earlier ousted from the mixed doubles competition, crashed out of the men's doubles with a stunning third-round loss.
The Indian and his Bahamian partner Mark Knowles, seeded fourth, squandered a set advantage to go down 6-2, 4-6, 4-6 to unseeded Argentines Maximo Gonzalez and Juan Monaco in the third round of the season's last Grand Slam.
There was further disappointment in the junior section where fifth seeds Yuki Bhambri and Serbian partner Filip Krajinovic lost 1-6, 6-5, 7-10 to Zimbabwe's Takanyi Garanganga and Egyptian Karim-Mohamed Maamoun in the first round.
