Jasmine Paolini became the first Italian woman in more than a decade to reach the final of her home Italian Open when she beat American Peyton Stearns 7-5 6-1 on Thursday.

Paolini is the first Italian to advance to the final in Rome since her doubles partner Sara Errani lost to Serena Williams in 2014.

Paolini had found herself a set and 4-0 down to Diana Shnaider in her quarter-final tie before storming to victory and once again the world number five had a slow start in the opening set before mounting a comeback.

"I am very happy, I don't know what to say! It's a dream to be here, it's a dream to play in Italy, it's a dream to be able to play the final," the 29-year-old said, according to Reuters.

Any hopes of a quick start for Paolini were put to rest when Stearns jumped into a 3-0 lead amid muted applause from the home crowd as the Italian soon found herself 4-1 down.

The American looked comfortable and poised to take the opening set before Paolini clawed her way back as she saved set points to level it at 5-5, pumping her fist with a triumphant scream that got the crowd roaring again.

The comeback was complete when Paolini, having won four games in a row, took the opening set after more than an hour of play.

The momentum was firmly with Paolini as she broke Stearns for a fifth time to go 4-1 up in the second set and the deflated American had no answer as the Italian's winners whizzed past her.

Stearns fired a forehand wide on match point as the crowd erupted and Paolini raised her arms in celebration.

"You (the crowd) gave me a boost because today it was a bit of an uphill start and I struggled at the beginning, thank goodness you were there," she added.

"We won this match together. Point after point I managed to fight, to turn it around, even if at the beginning I did not have a good feeling. But I am happy with the way I managed to turn this match around."
