The world number two from Serbia, looking to triumph at Roland
Garros for the first time, needed three sets - including two
tiebreaks - to down the Canadian in the semi-finals of the Rome
Masters last month.
They are scheduled second on Court Philippe Chatrier after Russian
Maria Sharapova, who faces a tricky test of her credentials against
Spain's Garbine Muguruza.
Unheralded Muguruza has been in great claycourt form, notably
defeating defending champion Serena Williams in the second round,
and she will not be afraid of last year's runner-up Sharapova.
Another Canadian, Eugenie Bouchard, faces Spanish 14th seed Carla
Suarez Navarro on Court Suzanne Lenglen as the 18th seed looks to
match her Australian Open performance after reaching the last four
in Melbourne this year.
They will be followed by Czech sixth seed Tomas Berdych and the man
who downed Roger Federer in the previous round, Latvian 18th seed
