At the 2014 Quidditch World Cup, Poland’s Wladyslaw Wolfke was beaten to the Snitch by Japanese Seeker Noriko Sato. The final score was 350 points to 140, although observers agreed that this did not reflect how well Poland had actually played (Pm).
Before the 2014 Quidditch World Cup tournament started, Poland's Seeker Bonawentura Wójcik was accused of actually being the Italian National Team's Seeker Luciano Volpi, disguised by Transfiguration. This was disproved by having the two appear together at a press conference. However, by the time of their first match against Japan on 21 May 2014, Wójcik had been replaced as Seeker by Wladyslaw Wolfke (Pm). This is never explained.
Although Poland is a Quidditch-playing nation, no Quidditch or any other wizarding sports teams are listed on their Wikipedia page (Wikipedia).
