As she took out marquee name after marquee name - Eugenie Bouchard, Caroline Wozniacki, Sabine Lisicki, Ana Ivanovic and, in an electric semifinal match on Saturday night, Serena Williams - Bencic became more and more of a crowd favorite as the week went on, and as she would say to the fans in her trophy speech, "Even if I lost today it would've been an amazing experience thanks to all of you."
But there was no letdown whatsoever in Sunday's final as Bencic stayed with the tenacious Halep for exactly two and a half hours before it all became just too much for the No.2-seeded Romanian, who succumbed to heat illness - Bencic would eventually win by retirement, 7-6(5), 6-7(4), 3-0.
"I don't think I'm so good at speeches yet!" Bencic said in her trophy speech. "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! 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."
Bencic now has two WTA titles, having won the Premier-level grass court event in Eastbourne in June.
She's the first teenager to win an event at the Premier 5 level or higher since Victoria Azarenka at Miami in 2009. She's also the first unseeded player to beat the Top 2 seeds at an event at the Premier level or higher since Justine Henin at Charleston in 2005 (Lindsay Davenport and Elena Dementieva).
The Swiss is also projected to rise from No.20 to No.12 when the new WTA Rankings are released.
And there's one more: Bencic is the second player to save match point en route to a title at the Premier level or higher this year - Andrea Petkovic saved eight match points at Antwerp in February.
Halep and Bencic will now go to Cincinnati for the second Premier 5 in as many weeks, the Western & Southern Open. Bencic, unseeded, will play Stanford champion and No.11 seed Angelique Kerber in the first round, while Halep, the No.3 seed, will get a first round bye before kicking off her campaign.
