"Of course I'm super happy to be in another final of the Grand Slam. Hopefully I can do a little bit better than the last time."

Having steadied herself, the reigning champion turned the tables in the tiebreak. With Gauff struggling to find her first serve, Sabalenka dominated the return and sealed a one-set lead after 57 minutes.

"I wish I could have made more first serves," Gauff said. "I think that was the difference. She had a higher first-serve percentage, and it's tough to also go for the second when you double-faulted a couple times.

"But that wasn't the fault, either. Because I put myself in the position, I cleaned up the first set, put myself in the position to serve out the set. At the end of the day, it came down to a couple of points."

Sabalenka served it out to close the 1-hour and 42-minute win. 

"I think in New York I played a little bit passive tennis," Sabalenka said. "I didn't put so much pressure her. I mean, I did in the first set, but then I kind of slowed down and started just trying to play rallies with her, which is not working well.

"The whole preseason I was working on those approach shots, on coming to the net and finish the point on the net. I'm super happy that I was able to do that on court today, and I think that's the difference between these two matches."
