Pospisil and Nestor teamed up in London 2012 but were eliminated in the round of 16. Nestor is looking to win his second Olympic medal in his sixth Olympic Games, having won gold in doubles at Sydney 2000.

Monday went much smoother for Nestor and Pospisil than their opening match on Sunday. Facing New Zealand’s Marcus Daniell and Michael Venus, the Canadians dropped the first set 6-4 before rebounding with a 6-3 victory in the second. In the third set, Daniell and Venus went up 5-4 and 6-5 but could not secure the match win. Nestor and Pospisil then went on to win a hard fought tie break 8-6.

On Monday, Nestor and Pospisil broke Elias and Sousa twice to quickly go up 4-0 in the opening set, going on to take it 6-1. The Canadians broke the Portuguese in the first game of the second set and went on to win 6-4, taking the match in straight sets.
