The unseeded duo clinched their maiden title in Internazionali BNL d'Italia in a 4-6, 6-0, [10-3] win.

"There were ebbs and flows a little bit, a few momentum changes in the match," Barty said.

"But I think that the way we started the second set, in particular, we were able to keep the foot down, keep the momentum going through the tiebreaker as well."

It's is the second consecutive double Rome title for Barty having won it with Schuurs last year.

However, on Sunday they became rivals with Barty and her partner Azarenka able to avenge a second-round loss to Groenefeld and Schuurs at last weeks Mutua Madrid Open.

The Australian/Belarussian duo got off to a hot start as they zoomed to a 3-0 lead, having broken after Groenefeld double faulted twice and fired a forehand error long on the deciding point.

But Barty double faulted on break point to cede the break back for 3-2, and the set turned.

This would allow Groenefeld/Schuurs to level the set before taking the lead at 4-3 and were able to close out the set two games later.

However, Azarenka/Barty were dominant in the second set with strong returns from the pair to break and lead 4-0. Groenefeld was unable to get her team on the board at 5-0, ending the set with back-to-back double faults.

The teams headed for the match tiebreak where Azarenka and Barty took complete command. 

The duo will have next week off from doubles action, then will reconvene in Paris to go for a Grand Slam title at the French Open.
