British number two Laura Robson claimed her first win in almost two years at a Challenger tournament in Canada.
Robson, 21, beat 17-year-old Japanese Naomi Osaka 7-6 (7-5) 6-7 (5-7) 6-3 at the Granby National Bank Challenger, a level below the WTA Tour.
The former world number 27 has fallen to 913th in the rankings after 18 months out with a wrist injury.
Robson lost in the first rounds at Eastbourne and Wimbledon on her comeback.
She was beaten 6-0 6-1 by Daria Gavrilova at Eastbourne in June - her first match since the Australian Open in January 2014 - and 6-4 6-4 by Evgeniya Rodina after being awarded a wildcard entry to Wimbledon.
