Belinda Bencic continued her amazing run at the Rogers Cup when she defeated Simona Halep in the final, following the Romanian's withdrawal on Sunday.
The Swiss was 7-6(5), 6-7(4) and 3-0 up in the final set when the scorching conditions in Toronto became too hot for Halep to handle.
The duo swapped breaks in the opening set, eventually forcing a tiebreaker. While the world number two ran out to a 4-1 lead, Bencic would battle back to make it 5-5 before winning the last two points to clinch the set.
Halep served for the second set at 6-5 up, but the world number 20 earned the crucial break to force another tiebreaker. This time, the second seed took her opportunity to win the set.
But Bencic fired off three quick games in the deciding set in just 13 minutes before the ailing Halep decided to call it a day.
"I don't think I'm so good at speeches yet!" quipped the 18-year-old during the trophy presentation.
"But first I want to congratulate Simona on a great week, and my mom, my dad and my team. And my fitness coach – I really needed my fitness today, so great job! And also Melanie Molitor, my coach – a big thank you to you too.
"And of course a big thank you to all the crowd. You were amazing in every match this week. It's just been such a special tournament, and I'll never forget it – I can't wait to come back next year."
The win concludes a dream run for Bencic, as she defeated fourth seed Caroline Wozniacki, former world number one Ana Ivanovic and 21-time grand slam winner Serena Williams en route to the final.
