Gonzalo Bueno is through to the round of 16 at the Challenger 125 de Costa do Sauípe in Brazil, a result that keeps his bid to finish the year inside the ATP top 200 alive. The Peruvian, ranked No. 198, advanced Tuesday when Colombia’s Daniel Galán, ranked No. 355, retired with physical problems while the second set stood at 5-5, the match having started with a 4-6 score in Galán’s favor, Infobae reported.

For Bueno, the win matters beyond the immediate prize money. A first-round exit in Brazil would have complicated his push to hold a spot among the world’s top 200 and to remain Peru’s second-ranked player. Instead, he moves on to face local favorite Eduardo Ribeiro of Brazil, ranked No. 360, with a place in the quarterfinals at stake.

How the match unfolded against Galán

The opening set went against Bueno. Galán took it 6-4, putting the Peruvian in a position where he had to win the second set to force a decider. Bueno battled back to reach 5-5 in the second, and it was at that point, with both players pushing to tilt the set, that the Colombian could not continue and withdrew from the match, according to Infobae. Ovacion, the Peruvian outlet, confirmed the same scoreline and retirement.

The result handed Bueno a walkover into the next round without the match being completed, a reminder of how quickly fortunes can shift in best-of-three Challenger tennis when fitness is a factor.

A 2026 season of highs and interruptions

Bueno’s place at No. 198 reflects a season that has swung between notable achievement and physical setbacks. His biggest result of the year came at the Challenger de Liberec in the Czech Republic, where he won the title by defeating local player Jan Kumstát in the final, Infobae reported. That triumph showed he can still produce at a high level when healthy.

But a lumbar injury interrupted his continuity on the circuit, and his return has required rebuilding rhythm and confidence. At the Challenger de Santa Cruz in Bolivia, he lost in his debut. He then collected wins in Cali and Guayaquil, though without advancing to the decisive stages of those tournaments. Costa do Sauípe, therefore, represents another chance to string results together and close the year on a stronger note.

Next up: Eduardo Ribeiro on Wednesday

Bueno’s next challenge comes against Brazil’s Eduardo Ribeiro, ranked No. 360, who carries the advantage of playing at home. Their round-of-16 match is scheduled for Wednesday, Nov. 4, at 1:00 p.m. Peru time, Infobae reported. A victory would send Bueno into the quarterfinals, add valuable ranking points, and move him closer to the later stages of the Challenger 125.

The stakes are clear: with two ranking spots separating him from the top-200 cutoff, every win in Brazil counts toward defending his position and restoring the consistency his game needs to end the season.

Varillas exits in the first round

The day was less kind to Peru’s other representative in the draw. Juan Pablo Varillas lost in the first round to Austria’s Filip Misolic 6-7(3), 6-3, 6-2, Ovacion reported. Varillas now turns his attention to the Lima Challenger, where he will look to rebound in front of a home crowd.

For Bueno, the question still open is whether he can convert this walkover into a deeper run. The answer begins Wednesday against Ribeiro in Costa do Sauípe.
