From August 2 to 9, Kozerki will once again become one of the most important tennis hotspots on the map of Poland. The entry list for the Mazovia Open ATP Challenger 2026 has been published. At this moment, it features 21 players representing 13 countries.
Polish fans will be able to cheer for Maks Kaśnikowski, among others. Maks has two ATP Challenger Tour titles to his name—won in Oeiras, Portugal, and at the Poznań Open. Daniel Michalski will also compete in Kozerki; in February 2026, he reached a career-high ATP ranking of No. 241.
The highest-ranked player on the published entry list is Damir Džumhur. The representative of Bosnia and Herzegovina was ranked as high as No. 23 in the world during his career and has won three titles on the main ATP Tour.
Kozerki will also host young players who are making an increasingly strong mark in professional tennis. Among them is Joel Schwärzler—a former world No. 1 junior, ATP Challenger champion in Skopje, and Roland Garros junior doubles champion.
The list also includes Harold Mayot. The Frenchman was the world No. 1 junior and won the Australian Open junior title in 2020. Also expected to compete in Kozerki are Alejandro Moro Cañas, Kimmer Coppejans, Daniil Glinka, Juan Pablo Ficovich, and Frederico Ferreira Silva.
