Stanislas Wawrinka has defeated Benoit Paire in three sets to progress through to the Rogers Cup third round.
The world number four looked in trouble when his French opponent took one of his four break-point opportunities to seal the early advantage in Toronto.
However, after the Australian Open champion responded in the second, he dominated a final-set tie-break against the world number 97 to record a 4-6 6-3 7-6 victory.
Wawrinka will play either Fabio Fognini or Kevin Anderson in the last 16.
