He's the youngest Brazilian to win an ATP title in the Open Era.

The Argentine’s victory over the world No. 2 at his hometown event on Friday was his first career win over a Top 2 player.

The Chilean was unable to follow up his semifinal win over Carlos Alcaraz Sunday, falling to the left-handed wild card, 6-3, 6-4.

Jarry, after the biggest win of his career, will face home crowd favorite Facundo Diaz Acosta in the final on Sunday.

The Chilean has now won four of his last seven matches against Top 5 players, a run that dates back to last May.

The 20-year-old No. 2-ranked player struggled with Andrea Vavassori's energy in the first set, but cruised to victory in the second on the outdoor clay courts.

The defending champion and top seed advanced to the quarterfinals of the Argentina Open by beating home hope Camilo Carabelli 6-2, 7-5 in his first clay-court match of the season.

The 38-year-old Wawrinka, who is ranked No. 60, was up a break in the third set and had a chance to serve it out in the 10th game but Jarry rallied and won the almost three-hour match in a tiebreaker.

Defending champion and top-seeded Carlos Alcaraz had a bye into the second round and will face Camilo Carabelli on Thursday, after the Argentine beat Peru's Juan Pablo Varillas 7-6 (5), 6-4.

The world No.60 overcame pressure from the home crowd Monday to beat Pedro Cachín 6-7 (4), 6-1, 6-2 at the clay court tournament in Buenos Aires.
