ISTANBUL — South Korea beat Colombia in a penalty shootout at the Under-20 World Cup Wednesday to join Ghana, Chile and Iraq in the quarterfinals. Having played out a 1-1 draw after extra time, Colombia was trailing 8-7 in the shootout when defender Daivy Balanta sent the last penalty over the crossbar. South Korea will now play Iraq, which needed extra time to beat Paraguay 1-0. Ghana and Chile will meet in the quarterfinals after both teams won their last-16 matches over 90 minutes earlier in the day. Ghana came from a goal down to beat Portugal 3-2 while two late goals earned the Chileans a 2-0 victory over Croatia. Balanta's spot-kick wasn't the only one that failed to find the net. Earlier in the series, Song Ju-hun missed for South Korea while Felipe Aguilar saw his attempt saved by goalkeeper Lee Chang-geun. Song had given South Korea the lead in the 16th minute when he beat goalkeeper Cristian Bonilla with a low shot after the Colombia defense failed to clear from the area. Colombia pressed long for an equalizer and had to wait until the fourth minute of injury time before captain Juan Quintero scored with a fierce free kick that beat Lee at the near post. The penalty shootout soon became inevitable as neither side was willing to take any risks by pushing forward in extra time. It was different story in the other late game, though, after Iraq and Paraguay has finished 0-0 after 90 minutes, with the South Americans having been reduced to 10 men in the 80th. Iraq substitute Farhan Shakor scored the only goal with a firm header past goalkeeper Diego Morel in the fourth minute of extra time. Paraguay, which defeated Argentina in qualifying, was without suspended captain Gustavo Gomez. It also lost Arnaldo Sanabria, who was booked in the 70th and sent off after another foul 10 minutes later. Brazil jumps to ninth Brazil has surged to ninth in the FIFA rankings after winning the Confederations Cup, rebounding from its historic low standing. The five-time World Cup winner and 2014 host had fallen to 22nd before a five-match victory streak earned the warm-up event title. World and European champion Spain tops the rankings despite its 3-0 beating from Brazil in the final last Sunday. Italy, third-placed at the Confederations Cup, climbs to No. 6. Uruguay rises seven to No. 12 after finishing fourth in the eight-team tournament. Germany follows Spain, and Colombia rises four to its highest-ever position of No. 3.

Tenth-ranked Belgium reaches its highest-ever position. England drops six to No. 15, losing its top-10 status for the first time since October 2008. Ivory Coast leads African teams at No. 13, and Confederations Cup entry Nigeria falls four to No. 35. Mexico is CONCACAF's best at No. 20, a fall of three places.
