With the win, Buse is now ranked 31st in the world.
Buse had the minor statistical advantage from a service perspective in the final. He had three aces and one double fault. Paul had one ace and three double faults.

It is also uncommon for a Peruvian to win an ATP title. The last male tennis player from Peru to win on the ATP Tour was Luis Horna, who defeated two-time Olympic gold medalist Nicolas Massu of Chile, 7-5, 6-3, in the final of the 2007 Movistar Open in Vina del Mar, Chile. Massu won gold in men’s singles and doubles tennis at the 2004 Olympic Games in Athens.
At the French Open, Buse will face Russian Andrey Rublev, the 11th seed, Rublev is known throughout the tennis world for going 0-10 in grand slam quarterfinal matches. This will be their first ever meeting head-to-head.
