Ignacio Buse grew up with a racquet in his hand in Lima — literally. He began at the Country Club de Villa, where his father, Hans, was a coach, and started the sport by age two or three. The bloodline runs deep: his paternal grandfather, Eduardo, and great-uncle, Enrique, were players after whom Lima's Estadio Hermanos Buse was named. A former No. 9 junior, he committed to the University of Georgia but turned pro instead, moving to Barcelona to train at the Tennis Empowerment Centre with 2002 Roland-Garros champion Albert Costa as a mentor.
He doesn't fit the South American mold. Despite the clay-country passport, Buse prefers an attacking game, enjoys faster surfaces, and dreams of Wimbledon or the French Open. The package is built on heavy topspin, court coverage and emotional control past his years, but the serve is the swing variable — he hits around 61% first serves with roughly six aces a match, balanced against just over three double faults, and converts close to half his break points. It's a counter-puncher's profile sharpened by a willingness to redirect pace rather than just out-grind.
The arc has been steep. He broke into the top 200 in May 2025, the top 100 in January 2026, and the top 50 in May 2026 at a career-high No. 31 after winning Hamburg to become the first Peruvian ATP Tour champion since Horna in 2007. The breakthrough came as a qualifier at the Hamburg Open, where he beat Flavio Cobolli, Jakub Mensik and Ugo Humbert before downing Tommy Paul in the final. That put him alongside Yzaga, Arraya and Horna as the only Peruvians ever to reach the ATP top 50. Earlier in the year he'd already announced himself at the Rio Open, reaching the semis with wins over local favorite João Fonseca and Matteo Berrettini.
As of June 2026 Buse sits at No. 35 — the clear face of Peruvian tennis, carrying the Davis Cup flag and a top-50 ranking into the back half of his first full tour-level season. The book on him is still being written; the early chapters are loud.
