Semi-tough? The women's hockey semifinals begin at noon when the United States takes on Sweden. The US, led by hat-trick specialist Jenny Potter, has been rolling, outscoring its three Group B opponents, 31-1. But if the US men's hockey team's instant-classic 5-3 victory over Canada last night wasn't reminder enough that upsets can happen, all the US women have to do is remember Turin, Italy four years ago, when they were stunned by -- yep, Sweden -- in the semifinals. 3 p.m.

And don't forget . . . Meryl Davis and Charlie White of the US enter tonight's free dance trailing Canada's Tessa Virtue and Scott Moir by 2.60 points in the ice dancing competition. Tanith Belbin and Ben Agosto of the US, silver medalists in Turin, are fourth. We're pretty sure there won't be any controversial Aboriginal costumes in this one, but I suppose you never know. 7:45 p.m.
