After spending an hour and 49 minutes splitting the first two sets, the first going to Bencic, 6-4, and the second going to Radwanska, 6-4, Bencic completely pulled away in the third set, needing just 24 minutes to take it at love for a 6-4, 4-6, 6-0 victory and the first WTA title of her blossoming career.
At 18 years and 109 days, Bencic is the youngest player to win a Premier-level title since New Haven back in 2008, where Caroline Wozniacki - 18 years and 43 days at the time - won her first Premier title.
"The match started very well for me, actually. I was very focused and I really played very freely," Bencic said afterwards. "Of course I was disappointed I didn't close out the second set, and I was also starting to get a little tired - it was a lot of running out there, and we had some long rallies out there too.
"But I was very focused in the third set, and after 3-0 I relaxed a little bit and closed it out well."
Next stop, Wimbledon - the Swiss teenager was asked how she feels about her chances.
"I play my first round on Monday, and I'm playing Pironkova, which is not an easy draw. She always plays great at Wimbledon," she said. "Tomorrow I'm just going to try to recover and practice a little bit, and then I just really need to focus on my first round. It's definitely not going to be an easy match.
"I have nothing to prove at Wimbledon. I just want to play relaxed and be satisfied with my results."
Bencic was playing in her third WTA final, having finished runner-up in her first two at Tianjin last fall (losing to Alison Riske) and at 's-Hertogenbosch just a few weeks ago (losing to Camila Giorgi).
Radwanska was still happy with her week, and her overall grass court lead-up season.
"I think I had a lot of good matches, Nottingham and here, and I think that's the main thing going into a Grand Slam," she said. "I think I did the best preparation I could before Wimbledon, and I played some really good tennis these last few weeks, so now we'll just wait and see what happens in London."
The doubles title went to No.4 seeds Caroline Garcia and Katarina Srebotnik, who fought off four set points down 5-4 in the first set and rallied from 5-2 down in the ensuing tie-break en route to a 7-6(5), 6-2 victory over the unseeded Taiwanese-Chinese pairing of Chan Yung-Jan and Zheng Jie.
It was Garcia and Srebotnik's first WTA doubles title together since joining forces at the beginning of the year. Garcia now has two WTA doubles titles to her name while Srebotnik has an amazing 36.
