Overview
- The 21-year-old is ranked No. 100 with 627 points in the January 5 ATP update, giving Peru its first Top 100 player since Juan Pablo Varillas in 2022.
- Buse did not enter Australian Open qualifying and is listed as the No. 2 alternate for the main draw, leaving any appearance dependent on late withdrawals and his fitness.
- He disclosed in mid-December that an injury halted his preseason, with his team assessing progress week by week and targeting a January return.
- Peru named Buse, Gonzalo Bueno, Juan Pablo Varillas and Arklon Huertas del Pino for the February 6–7 Davis Cup qualifier in Düsseldorf, while Germany’s squad includes Jan-Lennard Struff, Yannick Hanfmann, Tim Puetz and Kevin Krawietz.
- His rise was powered by 2025 Challenger titles in Heilbronn (C100) and Seville (C125) and steady results; in the latest rankings, Bueno sits at No. 214 and Varillas at No. 253.
