PORT ELIZABETH (Reuters) - David Suarez scored a goal in each half to give Uruguay a 2-1 win over South Korea on Saturday and take them to the World Cup quarter-finals for the first time in 40 years.

Uruguay took the lead when Suarez capitalized on some horrendous Korean defending, coolly slotting home an incisive cross from Diego Forlan that caught the entire defense napping.

Edinson Cavani neatly curled the ball out wide to Forlan, whose low pass cut through the sleeping Korean defense to the unmarked Suarez, who side-footed into an empty net.

Park Chu-young had almost drawn first blood in a bright start for the Koreans when his fifth-minute curling free-kick from 20 meters struck the upright with the keeper beaten.

Their celebrations were shortlived though. With just 10 minutes of normal time remaining, Suarez picked up a loose ball and curled in a superb shot off the post.

There was still time for the Koreans to almost force another equalizer when Lee Dong-guk's shot went through the keeper's legs but lacked the power to cross the line.
