Arjen Robben became the latest World Cup injury scare despite the Netherlands crushing Hungary 6-1 Saturday, while host South Africa boosted its hopes with a 1-0 warmup victory over Denmark. Robben limped off with a left hamstring injury after scoring twice in an impressive Dutch display in Amsterdam, with teammates fearing he could be the latest big star to be ruled out of the World Cup. After scoring twice in the Dutch triumph in Amsterdam, Robben went down injured trying some fancy footwork. After hobbling off the field he went to hospital for a scan. “He felt a sharp pain, that can't be good,” said Dutch coach Bert van Marwijk. “Treatment for these injuries has improved hugely, so I'm not giving up hope yet.” England defender Rio Ferdinand and Nigeria's John Obi Mikel have been ruled out with knee injuries and Ivory Coast striker Didier Drogba has had surgery on a broken arm to try and keep him at the World Cup. The star-studded casualty list also includes England's David Beckham, Germany's Michael Ballack and Ghana's Michael Essien. After Balazs Dzsudzsak gave non-qualifier Hungary a sixth minute lead in Amsterdam, the Dutch turned on the sort of attacking swagger they are renowned for. Robin van Persie equalized in the 22nd minute and Eljero Elia scored a memorable solo goal for the fifth. Wesley Sneijder and Mark van Bommel also hit the target. The Dutch, who also beat Ghana 4-1 Tuesday, appear to be building up to top form ahead of World Cup games against Denmark, Japan and Cameroon in Group E.

Gokhan Inler gave the Swiss a 10th minute lead but Fabio Quagliarella equalized four minutes later for an Italian side which begins its defense against Paraguay on June 14. Switzerland begins in Group H against tournament favorite Spain on June 16. Two goals by Edson Buddle in only his third game for the national team helped the United States to a 3-1 victory over Australia in the South African town of Roodeport. At the finals, the United States and England will face Slovenia and an Algeria side which ended a run of four losses with a 1-0 warmup victory over the United Arab Emirates with a second half penalty by Karim Ziani. In a seven-goal thriller in Belgrade, Serbia beat Cameroon 4-3 after twice falling behind to goals by Pierre Webo. Ghana's World Cup hopes have been hit by the absence of midfield star Essien who has been ruled out with a knee injury. But the team warmed up for the competition with a 1-0 victory over Latvia at Milton Keynes, England, substitute Quincy Owu.
