The United States women's national team tries to get back to another gold medal match when they take on Canada in the semifinal. They're so far undefeated in these games, although they really have only shown flashes of dominance. They've rallied against France, then pitched shutouts against Colombia, North Korea and New Zealand. Hope Solo has been part of those great efforts, although credit must also go to the improved USA defense.
The US will be heavily favored against Canada, who are one of the upstarts who managed to just qualify through group play. They upset Great Britain in their quarterfinal after a decent but hardly incredible performance in group play, but barring a huge miracle, the USA should be able to beat them to play the winner of France/Japan in the final. Solo's goaltending will be crucial against a Canada squad that gets their fair share of decent strikes.
The USA takes on Canada at 11:45 AM on the NBC Sports Network (also should be available uninterrupted on the NBC Soccer Network). The soccer should be streamed online on NBCOlympics.com live (and there should be a replay available).
