Daniel Vallejo makes history at Cincinnati Open

South American players saw mixed results at the 2026 Cincinnati Open. Paraguayan Daniel Vallejo made history by reaching the third round, marking the first time a Paraguayan player has achieved this feat at the tournament since 1983. Vallejo secured his spot by defeating Kyrian Jacquet and subsequently overcoming Monaco’s Valentin Vacherot in straight sets.

Argentine players also saw action, with Sebastián Báez securing a comeback victory against Grigor Dimitrov and Juan Manuel Cerúndolo defeating Mark Lajal. Marco Trungelliti also advanced after beating Hamad Medjedovic. However, Francisco Cerúndolo faced a difficult outing, losing his debut match to Nuno Borges after expressing significant frustration during training sessions regarding the North American hard-court tour.

In the women’s draw, Colombian Emiliana Arango recorded a notable victory over Venus Williams.
