Summer Ball is an international U13 softball tournament organized by Softball Club Princ in Zagreb since 2019. In 2026, we successfully hosted the 6th edition, welcoming 14 teams from different countries. Our goal is to give young players plenty of opportunities to play, gain international experience and make new friendships. Located at beautiful Jarun Lake, Summer Ball offers the perfect combination of softball, swimming, summer fun and unforgettable memories!
