Canada's Eugenie Bouchard and Gabriela Dabrowski defeated the Polish duo of Klaudia Jans-Ignacik and Paula Kania 6-4, 5-7, 6-3 in first-round women's doubles action at the Rio Olympics.
The Canadians won 67 per cent of their first service points, including 71 per cent in the decisive third set, in a match that went one hour 58 minutes.
Bouchard, from Westmount, Que., and Ottawa's Dabrowski converted seven of 11 break points, but only defended three of eight break points against.
Unforced errors were a problem for the Polish side. They committed six, while the Canadians finished with zero.
Bouchard and Dabrowski will next face the Czech duo of Lucie Safarova and Barbora Strycova, who upset the top seeded team of Serena and Venus Williams 6-3, 6-4 in the first round.
The win comes a day after Bouchard breezed past Sloane Stephens 6-3, 6-3 in singles competition.
In men's doubles action, Vancouver's Vasek Pospisil and Toronto's Daniel Nestor faced New Zealand's Michael Venus and Marcus Daniell.
