Sabalenka v Pegula
Jessica Pegula had never previously made it beyond the quarter-finals at a Grand Slam prior to this campaign at the US Open.
The 30-year-old could be excused for feeling her time would not come but she gets her moment in the spotlight tonight.
Victory at the Canadian Open in August suggested she was building momentum for Flushing Meadows and a run to the final of the Cincinnati Open provided further warning that she was in form.
"It's amazing. It's a childhood dream. It's what I wanted when I was a kid," Pegula said.
"It would mean the world to me to win. If you would have told me at the beginning of the year I'd be in the finals of the US Open, I would have laughed so hard."
