QUEBEC CITY, Canada - American qualifier Jessica Pegula's stunning run through the draw at the Coupe Banque Nationale présentée par IGA on Saturday, as she upset No.5 seed Sofia Kenin to reach her first career WTA final, 4-6, 6-2, 6-4.

Reaching her first championship match indoors in Quebec might've been written in the stars for Pegula, who last appeared in a WTA main draw at the event 12 months ago, and also reached the quarterfinals in 2016.

"I'm happy. I've been here since Thursday last week, so it's been a long week. I'm happy to get the job done, but I'm not too high," she said after the match.

"I've been playing a lot of tournaments lately, so I have been getting a lot of match play, and been doing pretty well, but this is probably the most amount of matches in a row."

On Saturday, the World No.227 scored her second upset over a seeded player this week, adding to a list of victories which included Kristyna Pliskova, Ons Jabeur and No.2 seed Petra Martic.

The 24-year-old served 10 aces and broke her younger compatriot five times in the match overall, scoring victory in just under two hours in her first three-setter of the tournament.

In an injury-plagued career - the latest of which saw her miss seven months of action last season - Pegula has been doing a fair bit of winning on the ITF Circuit in 2018.

She's reached five semifinals or better in ITF events this season, raising her ranking from World No.621 in January to her current position - and her run this week will see her at least rise back into the Top 150. 

"I feel pretty good physically, which has always been the No.1 thing [with me]. Today, I wasn't that sore or anything. I've had some pretty good wins already, so I knew I had the chance to win the match today. I'm excited and I'm just glad I got it done today," Pegula said of her first three-set match of the week.

"It's always good to come back, because you always want to win...but afterwards, it's always much more gratifying. It does something else for your confidence."

Unfamiliarity with opponent or situation hasn't stopped the qualifier's run this week, as her victories against Pliskova, Jabeur and Kenin came in her first career meeting against them.

Up next, she'll face another player for the first time in No.8 seed Pauline Parmentier, who also rallied from a set down to defeat Heather Watson in the day's second semifinal.
