The United States kept its hope alive for a fifth straight gold medal at the IIHF World Under-18 Championship in Sochi, Russia, with a 4-0 defeat of Sweden in the quarterfinals Thursday.

Thatcher Demko, a top prospect for the 2014 NHL Draft, stopped all 28 shots he faced, and four prospects for the 2013 draft -- Will Butcher, Tyler Motte, Michael McCarron and JT Compher -- supplied the offense in a game played at Shayba Arena.

The United States had beaten Sweden in the gold-medal game the past three years, and playing two rounds earlier in the 2013 tournament, the result was the same.
