Jelena Jankovic has come through a stern test in her opening match at the Rogers Cup, edging Anna Tatishvili in a hard-fought contest featuring fiery tempers.
The opening eight games featured two breaks of serve apiece, with Jankovic then coming close to a third break as Tashivili survived under pressure.
A tie-breaker was needed to separate the pair and it was Jankovic who prevailed, holding her nerve to claim the opening set.
Neither player could find consistency on serve, with a second set featuring seven breaks eventually going the young Georgian's way to force a decider.
Jankovic exchanged a series of heated arguments with the umpire as she found herself under pressure, but prevailed thanks to some effective serving.
The former Rogers Cup finalist eventually edged the qualifier 7-6(8) 4-6 6-3 to book a second-round clash with either Sharon Fichman or Stephanie Dubois.
