Jessica Pegula nears breakthrough but must wait to discover opponent.

Jessica Pegula reached her third WTA 1000 final of her career on Saturday, defeating world No. 1 Iga Swiatek 6-2, 6-7(4), 6-4 at the Canadian Open in Montreal.

It may be a watershed moment for Pegula, who has played consistently well over the last two seasons but has yet to win a huge game.

Pegula survived a tight struggle with the world's best player and is now one win away from the biggest championship of her career.                                                                                                                                                          

It was a great match," Pegula added. "It was difficult. It's like being on a roller coaster

I was really up and down, but I'm glad I was able to keep my cool towards the end.

Pegula came from 4-2 down in the third set to end her semi-finals losing run at the Canadian Open.

She might have thought she'd blown her chance after failing to serve out the match at 6-2, 5-4 in the second set, and 4-2 in the second set tiebreak.

The stadium sound system began playing 'Cotton Eyed-Joe' during that second set tiebreaker, forcing the point to be replayed.
