Ignacio Buse, 22, won the Hamburg Open final on May 20, defeating sixth-seeded Tommy Paul 7-6(6), 4-6, 6-3 to capture his first ATP Tour title [1, 2]. Buse became the first Peruvian to win an ATP Tour event since Luis Horna took the Chilean Open in 2007 [1, 2].

The qualifier struggled early, receiving treatment for dizziness and falling behind 4-0 in the second set before recovering to claim the deciding set [1, 2]. Buse said the win was emotional for his family and country: "This is for them. I feel extremely happy. It's the best feeling in my entire life for sure. I feel incredibly happy. I'm also really proud of Peru. It's the best country in the world, so I'm just so emotional now." [1]

Tommy Paul was denied his second title of the season after reaching the Hamburg final [1, 2]. Meanwhile, Learner Tien won the Geneva ATP title on May 21 by beating Mariano Navone to claim his second ATP trophy, becoming the youngest American man to win a European clay-court event since Michael Chang in 1989 [1, 2].

Emma Navarro captured the Strasbourg women’s title on May 21 with a 6-0, 5-7, 6-2 victory over Victoria Mboko. Navarro described her run as a comeback after a difficult year and a half of injury and illness: "It's kind of been a little bit of a rocky year and a half or so, but I think we've put in a lot of really good work."
