Erik Johnson scored twice during a four- goal second period, leading the United States to a 5-3 win over Austria in the 2013 World Hockey Championship.
Tim Stapleton, Aaron Palushaj and David Moss also scored for the Americans in their opener of the preliminary round. Ben Bishop stopped 18 shots in the victory.
The U.S. trailed 2-1 after the first period, but Johnson scored just 3:38 into the second to tie it and Stapleton put the Americans ahead at the 9:31 mark before Palushaj made it 4-2 just 1:26 later.
After David Schuller scored on a breakaway for Austria, Johnson found the back of the net again on a power play with 1:28 remaining in the second to restore a two-goal bulge. The Austrians managed just two shots in a scoreless third period.
The Austrians scored a pair of goals just a minute apart and led 2-0 just over 5 1/2 minutes into the game, but Moss cashed in a power play midway through the first to start the U.S. on its comeback.
