Costa Rica will compete at a FIFA women's finals for the first time in their history after qualifying along with favourites USA for the inaugural FIFA U-17 Women's World Cup New Zealand 2008.

The Ticas did so by providing the shock of last night's CONCACAF Women's U-17 Championship semi-finals in Trinidad and Tobago, claiming a 2-0 win over Canada that leaves the North American heavyweights to face off against Mexico for the confederation's third and final slot in Sunday's third-place play-off. Two goals within the space of five second half minutes from Katherine Alvarado and Fabiola Sanchez sealed victory for an unfancied Costa Rica side who had only just scraped through the group stage, opening the continental showpiece with a 6-0 drubbing at the hands of the US.

As for the Mexicans, even with star striker Charlyn Corral bolstering their ranks, they couldn't quite manage to spring another shock in last night's second semi-final, although they did take the much-tipped Americans all the way in a tight, tense encounter. Indeed, it was only after 92 deadlocked minutes that USA defender Crystal Dunn charged forward to score her first-ever international goal, settling the outcome and breaking the hearts of her side's cross-border rivals.

The US and Costa Rica will now do battle once again for the continental laurels in Macoya's Marvin Lee Stadium on Sunday evening (6pm local time), and will discover their fate at New Zealand 2008 the following day when the draw is made at the Home of FIFA to allocate the CONCACAF and CAF qualifiers to the groups drawn in Wellington last month.
