Jan Zieliński and Luke Johnson lose fourth consecutive match at Estoril Open

Polish player Jan Zieliński and British player Luke Johnson were eliminated in the first round of the ATP 250 Estoril Open in Portugal, falling 7‑6(3), 6‑1 to the French doubles team of Titouan Droguet and Kyrian Jacquet on the clay courts.

The loss represents their fourth straight defeat across recent events, following early exits at Bastad and Wimbledon. Entering Estoril as the top‑seeded pair, the duo was unable to reverse the slump despite holding two set points in the first set before the tiebreak.
