The World No.94 was the more composed player in her 6-2 6-3 victory, relying on her consistency to defeat a tired-looking Williams. After missing out on competitive singles action for close to a year, the 42-year old Williams appeared out-of-sorts in her second singles match since last August.

Teichmann steamrolled through the opening set, as Williams struggled to match her opponent's pace. The Swiss star employed the strategy of moving her the former World No.1 around the court, and opted to end most points with a short ball or drop short. An exhausted Williams was broken twice in the first set, as Teichmann ran away with the first set.
Williams displayed some of her trademark championship pedigree in the second set however, as both ladies exchanged breaks on two consecutive occasions to keep the score tied at 2-2. However, Teichmann obtained another break as Williams' game began to unravel, with the seven-time Grand Slam champion spraying errant shots in an attempt to shorten the points.

Serving to stay in the match at 3-5, Williams was unable to mount a comeback, allowing Teichmann to escape with the victory after an hour and 15 minutes. Nonetheless, the fans gave the former World No.1 a standing ovation on her departure, with many unsure on if they would see her return to Toronto again.
