Indian tennis players Sania Mirza and Leander Paes had a disappointing outing in the US Open on Friday with both losing their mixed doubles and men's doubles encounters, respectively.
Mixed doubles defending champions Mirza and Brazil's Bruno Soares lost 3-6, 3-6 to Czech Republic's Andrea Hlavackova and Lukasz Kubot of Poland in a first-round contest lasting 65 minutes.
Earlier on Friday, Paes and Spain's Fernando Verdasco lost their second-round men's doubles match 5-7, 6-4, 3-6 to unseeded American giant-killing pair of Steve Johnson and Sam Querrey, who eliminated the favourited Bryan brothers in the first round.
Paes and Verdasco got the better of Germans Florian Mayer and Frank Moder 6-2, 6-3 in their first-round encounter.
In women's doubles, the top-seeded Indo-Swiss pair of Mirza and Martina Hingis is scheduled to take on Switzerland's Timea Bacsinszky and her Taiwanese partner Chia-Jung Chuang in the second round.
