Ignacio Buse Revives Family Legacy With U.S. Open Victory, 68 Years After His Grandfather

Ignacio Buse opened his 2026 U.S. Open campaign with a five-set victory over American Marcos Giron, bringing the Buse family name back to the tournament 68 years after his grandfather last competed there.

The 22-year-old Peruvian, seeded No. 32, recovered from a slow start to beat Giron 3-6, 6-3, 6-3, 6-7(6), 6-1. The match, played in New York on September 2, lasted five sets and sent Buse into the second round of the hard-court Grand Slam.

The result was significant beyond the scoreboard. Eduardo Buse, Ignacio’s grandfather, played at the U.S. Championships in the 1950s. His final appearance came in 1958, when he defeated American Edward Atkinson before losing in the next round to Australia’s Mal Anderson. The U.S. Open highlighted that connection after Ignacio’s first-round win.

The elder Buse's own U.S. Open career ran deeper than a single generation-spanning coincidence. Eduardo competed at the tournament, then called the U.S. Championships, alongside his twin brother Enrique starting as early as 1942, and their matches were played on the outdoor grass courts of the old West Side Tennis Club in Forest Hills — a different surface, a different borough, and a different era of the sport than the hard courts of the current Flushing Meadows site where Ignacio now competes. The twins' standing in Peruvian tennis is commemorated today at Lima's Estadio Hermanos Buse ('Buse Brothers Stadium'), underscoring that Ignacio's run is less a novelty than the continuation of one of Peru's most established tennis families.

For the younger Buse, the victory followed a rapid rise through the professional ranks. Just days before arriving in New York, he won the Winston-Salem Open, an ATP 250 event, by defeating Britain’s Arthur Fery 6-3, 6-2. That title made him the youngest champion in Winston-Salem tournament history and marked his second ATP Tour trophy of the season.

The run also continued a breakthrough year for the Peruvian. The ATP Tour reported that Buse had climbed from No. 135 in the world one year earlier, while his performance in Winston-Salem helped establish him as one of the sport’s emerging players. At the U.S. Open, he entered the main draw as a seeded player for the first time in his career.

Against Giron, Buse had to manage the pressure of a match that repeatedly changed direction. He dropped the opening set, then took control by winning the next two. Giron forced a fourth-set tiebreak, but Buse dominated the deciding set and closed out the match with a 6-1 scoreline.

The victory was also a continuation of Buse’s family-based tennis education. According to the ATP Tour, his father, Hans Buse, coached him from an early age at the Country Club de Villa in Peru. Ignacio began learning the game as a young child, building the foundation for a professional career that has now brought him back to the same Grand Slam stage once occupied by his grandfather.

Buse’s next challenge is France’s Benjamin Bonzi in the second round. The match gives the Peruvian an opportunity to extend a U.S. Open campaign that has already delivered a personal milestone and a compelling family reunion across generations.

Buse has not won the U.S. Open tournament itself; his achievement so far is a first-round match victory and advancement to the second round. But for Peru and the Buse family, the moment carries a larger historical meaning: 68 years after Eduardo Buse competed in New York, Ignacio is writing the next chapter.
