Rio de Janeiro, Brazil – February 20, 2026 – The Rio Open presented by Claro, a premier ATP 500 clay-court event, delivered a day of gripping drama and significant upsets on Thursday, as reported by sportsamo.com. In a stunning turn of events that captivated the home crowd, Peruvian rising star Ignacio Buse defied expectations to defeat Brazilian hopeful Joao Fonseca, 5-7, 6-3, 6-4, in a hard-fought second-round encounter. Alongside Buse’s breakthrough, seasoned Italian Matteo Berrettini continued his impressive comeback, while Argentina’s Tomas Martin Etcheverry and Portugal’s lucky loser Jaime Faria also secured their spots in the quarterfinals, setting the stage for an electrifying weekend of tennis in the Marvelous City.
Buse’s Breakthrough: A Star Emerges on the Clay
The spotlight in Rio de Janeiro shone brightest on the highly anticipated clash between local sensation Joao Fonseca and the determined Ignacio Buse. Fonseca, a darling of the Brazilian tennis scene, entered the match burdened by the immense expectations of a passionate home crowd, eager to see their prodigy advance deep into an ATP 500 tournament. The 20-year-old, known for his explosive game and charismatic presence, had been touted as a potential future star, and his wild card entry into the main draw had fueled national hopes. However, Buse, a 21-year-old Peruvian who has been quietly climbing the ranks, had other plans.
The match began with Fonseca asserting his presence, leveraging the crowd’s energy to snatch the first set 7-5. His powerful forehand and aggressive approach seemed to put Buse on the back foot. Yet, the narrative shifted dramatically as the Peruvian found his rhythm, demonstrating remarkable composure under pressure. Buse capitalized on an uncharacteristic surge of unforced errors from Fonseca, tallying 43 throughout the two-hour, 26-minute battle. This tactical shift, combined with Buse’s exceptional defensive skills and ability to convert crucial points, allowed him to seize control of the second and third sets, 6-3, 6-4.
"Today was a really difficult match," Buse reflected after his career-defining victory. "We all know the potential that Joao has. We are really close friends, so that was also hard today." This poignant comment underscored the personal challenge of competing against a friend, especially one with such high stakes. What truly set Buse apart was his remarkable resilience on break points, saving eight of the nine he faced. Key moments included fending off three break points in the opening game of the second set, a critical juncture that could have derailed his momentum, and another three at 4-3 in the deciding set, showcasing nerves of steel. The Peruvian sealed the upset with his eighth ace, a fitting end to a meticulously played match. This victory marks a significant milestone for Buse, who became the first Peruvian to reach an ATP 500 quarter-final since the series was introduced in 2009. His rapid ascent from No. 230 to a career-high No. 91 in the PIF ATP Rankings within a year speaks volumes about his dedication and potential, echoing the success of previous Peruvian talents like Luis Horna and Jaime Yzaga in different eras of professional tennis.
Berrettini’s Resurgence: Italian Power on Clay
In another compelling second-round encounter, Matteo Berrettini continued his inspiring return to form, overcoming a challenging Dusan Lajovic 3-6, 6-4, 6-2 in two hours and nine minutes. The Italian, a former Wimbledon finalist and a potent force on all surfaces, has endured a challenging period marked by injuries that saw his ranking slide. His appearance in Rio, a tournament known for its physically demanding clay courts, was a testament to his determination to reclaim his place among the elite.
Lajovic, an experienced Serbian clay-court specialist, presented a formidable challenge, showcasing his consistent groundstrokes and tactical acumen to take the first set. However, Berrettini, known for his powerful serve and devastating forehand, refused to yield. He incrementally raised his level, finding his rhythm and asserting his physicality as the match progressed. The second set saw a tighter contest, with Berrettini leveraging his big serve to gain an advantage and eventually break Lajovic to level the match. By the third set, the Italian’s confidence was soaring, and his superior firepower overwhelmed Lajovic, culminating in a dominant 6-2 finish. This hard-fought victory marks Berrettini’s first tour-level quarter-final on clay since his triumphant run to the Kitzbuhel title in 2024, a clear indication that "The Hammer" is regaining his top form and is a serious contender once again. His quarter-final clash against the in-form Ignacio Buse promises to be a fascinating battle of experience versus raw, ascending talent.

Etcheverry’s Steadfast March and Ranking Climb
Eighth seed Tomas Martin Etcheverry, a formidable presence on clay, navigated his way into the last eight with a solid 7-6(1), 6-4 win over Lithuanian qualifier Vilius Gaubas. Etcheverry, a player who has consistently performed well on the dirt, came into the tournament with expectations of a deep run. Gaubas, on the other hand, was playing in uncharted territory, aiming for his first tour-level quarter-final and having already exceeded expectations by making it through qualifying and winning his first-round match.
The first set was a tightly contested affair, decided by a tie-break that Etcheverry dominated, winning 7-1, showcasing his mental fortitude in crucial moments. The second set, however, provided its share of drama. Etcheverry appeared to be cruising, holding a match point on Gaubas’s serve at 5-2. But the young Lithuanian fought back, denying the Argentine. As Etcheverry stepped up to serve for the match, rain unfortunately suspended play, adding a layer of tension. Upon returning to the court, the Argentine was broken, allowing Gaubas a lifeline. Yet, Etcheverry immediately regrouped, breaking Gaubas back to seal the match in two hours and seven minutes. This demonstration of resilience, especially after the rain delay and the unexpected break, highlighted Etcheverry’s mental toughness and competitive spirit. With this victory, the Argentine is projected to climb to No. 44 in the PIF ATP Live Rankings, securing a much-anticipated return to the Top 50 for the first time since April of the previous year – a significant boost for his season goals. He will now face the tournament’s surprise package, Jaime Faria.
Faria’s Fairytale Run Continues: From Lucky Loser to Quarter-Finalist
Perhaps the most compelling narrative of the tournament thus far belongs to Portugal’s Jaime Faria, who, as a lucky loser, has transformed an unexpected opportunity into a dream run to the quarter-finals. Faria’s journey began with a monumental upset in the first round, where he defeated two-time defending champion Sebastian Baez. Baez, a consistent performer and a clay-court specialist with a strong track record in Rio, was considered one of the favorites, making Faria’s victory a significant statement win and undoubtedly the biggest of his burgeoning career.
Carrying that momentum, Faria faced the experienced Bosnian Damir Dzumhur in the second round. Dzumhur, known for his unconventional style and ability to frustrate opponents, presented a tricky challenge. However, Faria, brimming with confidence, maintained his composure and continued his impressive form. He secured a 7-6(1), 6-4 victory over Dzumhur in two hours and three minutes, once again showcasing his ability to perform under pressure, particularly in the crucial first-set tie-break. Faria’s unexpected success as a lucky loser underscores the unpredictability and depth of the ATP tour, where every opportunity can be seized.
