Pegula needed only 49 minutes to become the first American to win the Canadian Open in a decade, since Serena Williams' victory in 2013.

World number 18 Samsonova had an incredible week by claiming two top-five scalps, Aryna Sabalenka and Elena Rybakina.

But she had spent nearly ten hours on court and those efforts took a toll as Pegula, who had beaten world number one Iga Swiatek in the semi-finals, comfortably claimed her third career title.

Pegula acknowledged that Samsonova - who had to battle through her rain-dealyed three-set semi-final earlier in the day - was fatigued, but she still didn't give her opponent any chances.

"I know obviously physically she wasn't feeling her best, but at the same time I played a really clean match," added Pegula.

"I don't really think I made any unforced errors or anything. I played kind of a perfect match.

"I feel like I did enough to where, yeah, I could just play freely, and I kept trying to get the break and just hold for as long as I could until I won the match. It was a good day."

Reflrecting on the week, Pegula was proud for having claimed two big scalps in her way to the title.

"We're out on tour to win tournaments and to win titles every single week, but tennis can be really tough where you sometimes lose a lot," she continued.

"Even when you're winning a lot of matches, you're still not winning tournaments, so it can get tough.

"Beating Coco and beating Iga were two really tough wins back-to-back, and being able to do that and then just come out today and play a really clean match was kind of great. I felt like I didn't have a ton of pressure at any point or I wasn't worried too much today.

"Winning a week like this week makes it all worth it and makes you want to keep going for more. I'll be right back at it tomorrow in Cincinnati."
