Swiss youngster Belinda Bencic has won the Rogers Cup in Toronto after her opponent, Simona Halep, was forced to retire in the final with an injury.
The 18-year-old, who won her first tour title at Eastbourne this summer, took the first set on tie-break.
Bencic, who beat Serena Williams in the semi-final, had led 5-3 in the second set, but Halep was able to break back before winning the set 7-6 and forcing a decider.
However, the second seed struggled with the heat and required treatment on a leg injury.
After losing her first two service games in the third set, Halep decided she could no longer continue, handing the Swiss youngster her second WTA title.
As a result of her victory in Toronto, Bencic will move up from 20th to 12th in the latest world rankings.
