Eugenie Bouchard was eliminated from the National Bank Cup on Thursday night, falling 6-2, 6-3 to Russia's Alla Kudryavtseva in the second round.
Bouchard, the tournament's top seed, won only one break point in six tries against the 162nd ranked player in the world.
The 22-year-old also saved just 3-of-8 break points. Bouchard, who was ranked as high as No. 5 in the world two years ago, is now ranked 48th.
Kudryavtseva was efficient on her first serves, winning 81 per cent of the points and broke the Westmount, Que., native twice in the first set.
Bouchard's game didn't improve in the second set as she struggled with her service game. Bouchard was able to get close by breaking Kudryavtseva to make it 5-3 but then failed to record a point while on serve in the next game, handing the victory to the Russian.
According to Radio-Canada's Jean-Philippe Martin, Bouchard was booed by some as she left the court. The crowd also appeared to jeer Bouchard by loudly cheering for the Russian on the final point and after the match.

Bouchard reportedly left the stadium immediately without speaking to the media.
In other matches on Thursday, Montreal native Francoise Abanda fell in the second round 7-6, 7-5 to American Jessica Pegula. Abanda's defeat means that all Canadians have been eliminated from the tournament.
Earlier in the day, Alison Van Uytvanck of Germany defeated Russia's Barbara Stefkova 6-4, 6-3 and Oceane Dodin of France got past Sachia Vickery of the U.S., 6-4, 6-4.
