Overview
- The 22‑year‑old Peruvian 32nd seed defeated American Marcos Giron in five sets on Wednesday, winning 3-6, 6-3, 6-3, 6-7(6), 6-1 after three hours and 48 minutes on Court Six.
- Buse closed the match with a decisive backhand volley that drew loud cheers from his team and fans and highlighted his physical stamina and shot execution in the decider.
- He said staying calm was key in the final set, stressing the mental battle of long matches as he converted recent tour form into a Grand Slam breakthrough.
- Buse arrived in New York after winning the Winston‑Salem Open the prior week, and his second‑round opponent will be Frenchman Benjamin Bonzi.
- The victory revived a family link to the tournament: his grandfather Eduardo Buse last won a U.S. Open match in 1958 and is honored in Lima at Estadio Hermanos Buse, a tie that underlines Peru's smaller but proud tennis history.
