New York: In what would come as a massive blow to India's chances in the Davis Cup, tennis ace Leander Paes pulled out of the US Open mixed doubles semifinals due to back spasms which also makes him doubtful for the World Group playoff tie against Japan next week.
Paes and his Russian partner Elena Vesnina, seeded seventh, gave a walkover to unseeded Americans Melanie Oudin and Jack Sock in the mixed doubles semifinals due to the Indian's back problem.
"Rough day for Leander, back spasms during the doubles. Out of mixed and now in doubt for Davis cup too..hmmmm," tweeted his men's doubles partner Mahesh Bhupathi.
Paes and Bhupathi were knocked out of the men's doubles quarterfinal after losing to Poland's Mariusz Fyrstenberg and Marcin Matkowski in straight sets.
The sixth seeded Polish duo won 6-4 7-6 (7-4) in an hour and 43 minutes against the fourth seeded in Indian pair.
India's Davis Cup tie against Japan is scheduled from September 16 to 18 in the Japanese capital of Tokyo.
