|Grzegorz Grochowski led Poland in assists at last year's U20 European Championship Division B|
Despite their basketball tradition, the central European nation have never competed in the top flight of this age category but with the core of last year's U20 team returning this summer, Poland can only be considered as early favourites to reach the final in the tournament that will be hosted in Romania.
The fact that head coach Mariusz Niedbalski has included in his 26-man strong preliminary team the most promising young players in the country serves as the best proof that Poland aim to finally earn promotion this summer.
All five talented players were on the U20 team last year, as 19-year-olds at the time, when Poland finished in fifth place and just missed out on a top-four finish that would have seen them gain Division A status for the first time.
Ponitka had led the team in scoring (15.8 ppg) and rebounds (7.9 rpg) while Grochowski finished the tournament with a team-high 6.2 assists.
The U20 European Championship Division B tournament will be staged in Pitesti from 12 to 21 July.
The Poles were drawn in First Round Group A, together with the Slovak Republic, Great Britain, Luxembourg, Hungary and hosts Romania.
