The winners of last year's WorId Championship title in Iquique in Chile overcame Portugal at the Roller Skate Park.

It was a repeat of last year's final in the Chilean city and Spain once again proved too strong for their neighbours, claiming a 4-1 win.

Argentina are also through to the last four as they inflicted another brutal defeat onto the United States.

The Americans had shipped 62 goals without scoring one before today's match and that record got even worse when Argentina hammered them 10-0.

Joining them in the semi-finals are South American rivals Chile, as they saw off France 3-0.

Completing the line-up is Germany after they also eased to a 3-0 win over Italy.

Spain's dominance extended into the men's under-20 rink hockey competition.

They moved into the semi-finals of that event as well with a dominant 9-0 win over England.

Argentina defeated Chile 4-1 to progress while Italy brushed aside Colombia 5-0.

Portugal complete the semi-final line-up after they defeated France 7-4 in a thrilling match.

It is due to be held until September 10 and will feature different competitions held at indoor and outdoor facilities.
