John Gibson, NHL Central Scouting's top-rated North American goaltender for the 2011 Entry Draft, stopped 30 of 31 shots as the U.S. beat Switzerland 2-1 Thursday in its opening game at the IIHF World Under-18 Championship, in Crimmitschau, Germany.

Reid Boucher, No. 113 on Central Scouting final ranking of the top North American skaters, scored the deciding goal at 5:09 of the third period. Boucher one-timed a pass from Jonathan Miller behind Switzerland goalie Luca Bolthauser.

Ryan Haggerty also had a goal for the U.S., which is the two-time defending champion at this tournament.

"Tonight we found a way to win a very difficult game," U.S. coach Ron Rolston told USA Hockey's website. "Every game we play will be a battle, so getting three points tonight was a good start."
