Buse survives Berrettini, rain delays in Rio de Janeiro’s QFs

Etcheverry claims 100th victory and sets up a clash in the Kopriva semi-finals

February 21, 2026

Ignacio Buse added another memorable moment to his Rio Open 2026 presented by Claro on Friday.

One day after upsetting third seed and home favorite Joao Fonseca, the Buse defeated former No. 6 player in the PIF ATP Rankings Matteo Berrettini for a 6-3, 2-6, 6-2 victory in a rain-affected quarter-final at the ATP 500 on clay. With the victory he advanced to the biggest semi-final of his career.

“Today was really tough because we stopped, I think, four times because of the rain,” Buse said. “The conditions are sometimes fast, sometimes slow. You never know. But it was a difficult match, but I’m happy that I did well.”

At 5-2 in the third set, the Peruvian was on the brink of victory before rain disrupted the match for the fourth time. When he resumed play, he dropped two match points on Berrettini’s serve before eventually taking victory in two hours and 19 minutes.

In his first Lexus ATP Head2Head clash with the Italian, Buse saved four of the six break points he faced, according to Infosys ATP Stats. The 21-year-old will face Alejandro Tabilo for a place in the final.

Watch extended highlights:

Tabilo, the former No. 19 player in the PIF ATP rankings, won the final match of the day against Thiago Agustin Tirante 7-6(2), 6-7(6), 6-1, reaching the finish in two hours and 53 minutes. The southpaw has won 10 of his past 11 matches at all levels.

In another quarterfinal, eighth seed Tomas Martin Etcheverry secured a milestone victory. The 26-year-old defeated lucky loser Jaime Faria 7-6(4), 6-4 to earn his 100th victory at tour level. The Argentinian crucially saved all five break points he faced in the first set.

“It was a tough tiebreaker,” Etcheverry said. “In the end I played well in the tiebreak. And I think I played better in the second set than the first.”

In the semi-finals, Etcheverry will face Vit Kopriva, who eased to a 6-4, 6-4 win against Juan Manuel Cerundolo in which he did not face a break point. By beating Cerundolo, Kopriva reached his second tour-level semi-final, five years after reaching his first on his ATP Tour debut in Gstaad in 2021.
