Boston Bruins goalie Jeremy Swayman remained undefeated at the World Championship and was a brick wall for Team USA on Sunday and helped the Americans to its first gold medal in the tournament since 1933.

Swayman stopped all 25 shots he faced in the 1-0 overtime win.

The goalie was 6-0 entering Sunday's game with a .905 save percentage and 1.98 goals-against average, and finished 7-0 with a .920 save percentage and 1.69 GAA.

Swayman's strong tournament comes after a down season between the pipes in Boston. He went 22-29-7 with a 3.11 goals-against average and .892 save percentage.

"I couldn't be happier to be at this tournament, especially based on the year I had," Swayman said in Sweden, via The Hockey News. "I feel like a completely new human being and a completely new goalie. The guys in this room have been so incredible for just supporting me, and it's just been a contagious locker room of joy. I just feel like a completely new human being."

Bruins defensemen Mason Lohrei and Andrew Peeke also earned gold.

The gold medal game was quite the goalie duel and needed overtime to decide the winner.

Buffalo Sabres center Tage Thompson scored the golden goal 2:02 into overitme to lift the Americans to a win over Switzerland.

In the bronze medal game between Sweden and Denmark, Bruins center Elias Lindholm had two assists to earn the bronze.
