Kaminski and partner Bartosz Januszewski defeated top seeds Jan Ochedalski and Franciszek Bruno Tusinski 12-5, 10-12, 12-4 in the semi-finals. 

Duszak and Franczuk battled to a 12-7, 9-12, 13-11 victory in the gold medal match. 

"First of all, I am very happy to be able to compete in tournaments in the current situation," Duszak said.

"In the singles category I had no problems in any match, and I managed to win without losing a set. 

"In the doubles category, together with Bartlomiej Franczuk, we made a lot of mistakes in key moments, but we won 2-1 in the final.

"We know that there is a lot of work ahead of us, so we will focus on training hard for the next tournaments."

Kaminski finally achieved a gold medal to add to his two silvers in the mixed doubles, pairing with Ewa Krol to overcome Franczuk and Alicja Bartnicka 12-8, 12-6.
