At 14-years-old, Balcerowski became pro in Poland and made his professional debut by 17-years-old to become the second-youngest player to be on the men’s Gran Canaria team.

In 2021, Balcerowski declared for the NBA Draft but withdrew himself to join the KK Mega Basket for the 2021-22 season. He returned back to Gran Canaria for 2022-23.

Balcerowski finished the season averaging 61.8 percent shooting from the floor.
