Both teams broke each other once in the first set to take it into a tie-breaker. Paes and Dlouhy held their nerve in the keenly fought tie-breaker to take the lead.

The second set was also closely contested with both pairs holding their serve to stretch it to another tie-breaker that the Indo-Czech pair managed to close out.
