Gauff had lost three times to Paolini in 2025 and on top of that, the world No.8 had just dominated No.2 seed Iga Swiatek 6-1, 6-2 in the quarter-finals.
The American, just like so many instances before, shrugged off outside noise, ignored the form book or head-to-head narrative and secured a 6-4, 6-3 victory over Paolini to head into the silverware showdown versus Pegula.
Over the net, Pegula was in a confident streak of form, having toppled world No.1 Aryna Sabalenka 2-6, 6-4, 7-6(2) in a last four thriller.
In the final, Gauff portrayed plenty of grit to reel in Pegula from 3-0 down and 5-3 down in the second set to break clear for an 11th WTA crown.
“When I came on tour, you were one of the first people to be nice to me and welcome me with open arms,” said Gauff, hailing Pegula during the trophy ceremony. “That really went a long way, so I appreciate you. It’s great to finally play in the final against you, and I hope for many more.”
Gauff and Pegula can now look ahead to a WTA Finals title tilt early next month.
