Stefan Mielzynski is ending the 2018 season on the diamond.

The heavy-hitting Fieldhouse Pirates first baseman has been selected to join the Polish National Team, as they travel to Los Angeles this week. While in California, the team is playing a series of exhibition games as an informal tryout camp for the Polish team that will compete in the European Championships in the Summer of 2019.

Poland, who currently sits 39th in the World Rankings, will play club teams from UCLA, Cal. State Fullerton, St. Francis/Arcadia and more.

Mielzynski, 18, is the youngest rostered player on the team.
