The Santiago native faces 2017 champion Alexander Zverev in his biggest career final Sunday.

Nicolas Jarry is one win away from becoming Chile’s first ATP Masters 1000 champion in 25 years.

On Friday, the No. 21 seed overcame 14th-seeded Tommy Paul, 6-3, 6-7 (3), 6-3, for his third three-set victory in his run to the Rome final. With grandfather Jaime Fillol cheering him on, Jarry regrouped after dropping the second set from a set and a break up. He held his nerve in the final game, saving two break points in between needing five match points to shut the door on Paul and dampen his 27th birthday.

“I was not very happy at the end of the second set,” Jarry admitted to press in the mixed zone afterwards. “I tried to use that energy to push myself and to focus it on my tennis, on what I need to do, and try to play as best I can. That gave me the break and more confidence to continue and to close the match.

“Tommy doesn’t make you feel comfortable on the court, so I made it through and that’s the best thing about it.”

The last Chilean player to win a 1000-level title was Marcelo Rios at 1999 Hamburg, the former world No. 1’s fifth triumph at that level. Jarry will look to join him on the Internazionali BNL d’Italia honor roll, as Rios was crowned the 1998 winner when Albert Costa withdrew prior to their final with a wrist injury.

In the quarterfinals, Jarry picked up his third Top 10 victory of the season by ousting Monte Carlo title holder Stefanos Tsitsipas. The boisterous crowd at the Foro Italico was one of the factors in pushing him across the finish line then and against Paul.

“Yesterday and today were amazing. I was hoping it was going to be like yesterday. Yesterday was my first day in the stadium. It was quite a shock. But I enjoy this atmosphere, I like it,” said Jarry.

His nation nearly had two reasons to celebrate on the day, before Alexander Zverev crashed the party. After getting outplayed early, the 2017 champion stormed past Alejandro Tabilo, 1-6, 7-6 (4), 6-2.

“He’s a tough, tough guy to beat. Amazing backhand, good serve. He’s playing very good tennis right now,” assessed Jarry about his upcoming opponent.

In turning the tide, Zverev has now won his past 18 matches against left-handers. The No. 3 seed is 21-11 lifetime in tour-level finals.
