The United States, led by four saves in a shootout by Guy Hebert, beat Canada, 5-4, yesterday in Tacoma, Wash., and moved into the gold medal hockey game.

The U.S. team will play the Soviet Union, a 4-1 winner over Sweden, for the championship.

Tim Sweeney and Tony Amonte scored in the shootout, which followed a 10-minute scoreless overtime. Sweeney, of Salt Lake City in the International Hockey League, put a shot between the legs of goalie Warren Sharples on the first attempt in the shootout. Amonte's wrist shot beat Sharples to the stick side.

Canada tied the game on a goal by Kent Manderville with 6:32 left in the third period. Tom Pederson of Minnesota had put the Americans ahead, 4-3, earlier in the period.

Shawn McEachern had two goals for the U.S. team.
