The Poland striker added a third goal two minutes into the second half with a simple low finish from near the penalty spot and Pablo Torre made it 4-0, having capitalised on an error by Barbastro goalkeeper Arnau Fabrega.
Aragonian club Barbastro sit 16th in Group Two of the Segunda Federacion, three points into the relegation zone.
