Mazovia Open ATP Challenger launches in Kozerki, Poland with €97,600 prize fund

The Mazovia Open ATP Challenger 2026 takes place from 2 to 9 August in Kozerki near Grodzisk Mazowiecki, Poland. Backed by the Mazovian Marshal's Office, the event offers a total prize pool of €97.6 k and features a new VIP Silver covered stand, family zones, and the ELC Live line‑calling system using over 70 cameras.

The player field includes former world No. 23 Damir Džumhur, several Polish competitors such as Maks Kaśnikowski, Daniel Michalski, Tomasz Berkieta and Adam Majchrzak, as well as other international entrants. In the singles draw, Kaśnikowski was eliminated in the quarter‑finals, leaving Filip Pieczonka as the sole Polish player still competing, now in the doubles draw with Morocco’s Younes Lalami Laaroussi. Rain caused a brief suspension of Kaśnikowski’s match against Spain’s Ivan Marrero Curbelo.
