The star pair of Leander Paes and Martina Navratilova was ousted by Nenad Zimonjic of Serbia and Montenegro and Katarina Srebotnik of Slovakia in the mixed doubles quarterfinals of the US Open on Monday.
Paes and Navratilova, seeded seventh, lost a tight third set tie-breaker to concede the match 6-7(2), 7-5, 6-7(9) in over two hours.
Zimonjic, who was Paes' men's doubles partner, and Srebotnik served better than their more experienced opponents and squeeezed out two tie-break wins to advance into the semi-finals.
