“I came here as a kid to watch this tournament so to lift the trophy is beyond what I ever dreamed of.”

Neither player was able to hold serve in the opening three games before Paolini’s nerves eventually settled as she took a 3-1 lead.

That was the point at which Paolini upped the ante as she closed out the set in emphatic fashion.

Paolini raced into a 3-0 lead in the second set with two early breaks before Gauff claimed a break back and then managed to hold her serve.

However, Gauff was unable to wrestle momentum back her way as Paolini swaggered through the remainder of the set.

Guaff saved one match point but, at 40-30, Paolini sealed victory with a powerful serve down the middle.

Victory means she will move up a place to fourth in the world rankings on Monday and obtain a top-four seeding for the French Open, which begins next weekend.

She and Sara Errani take on Veronika Kudermetova and Elise Mertens in Sunday’s women’s doubles final.

Monica Seles was the last woman to win the singles and doubles tournaments in Rome in 1990, while the only player to do so in a WTA 1000 series tournament was Vera Zvonareva at Indian Wells in 2009.

Paolini’s compatriot Jannik Sinner will contend the men’s singles final against rival Carlos Alcaraz on Sunday.
