Ricardo Quaresma scored the winning penalty as Portugal beat Poland 5-3 in a shootout to reach the semifinals of the European Championship on Thursday.Having previously scored an extra-time winner in the round of 16 against Croatia, Quaresma's penalty sent Portugal into the semifinals for the fourth time in the last five European Championships.Poland winger Jakub Blaszczykowski came into the match at the Stade Velodrome as his team's top scorer. But he had a poor game and saw his penalty saved one-handed by Rui Patricio, allowing Quaresma to finish the job with the very next kick in front of a stand packed with Polish fans.
