Curtis Dickson drove to the cage to pull Canada within one again early in the fourth quarter, but Rob Pannell then scored on a nifty back-handed shot to give the U.S. a 9-7 lead with 15:54 remaining.
Canada then scored three straight goals, taking its first lead of the game at 10-9 as Ben McIntosh streaked down the alley and finished a feed from behind the cage by Mark Matthews with just 5:10 remaining.
The U.S. responded to the challenge. Matt Danowski took a feed from Paul Rabil and ripped home a sidearm rocket to tie the game 10-10 with 3:04 left in the game.
Greg Gurenlian won the ensuing draw and the U.S. called timeout.
The U.S. turned it over, but Canada turned it over back to the U.S. on the clearing attempt giving the U.S. offense another chance.
Rabil, a two-time all-world honoree and the MVP of the 2010 FIL World Championship, spun his man around and buried an outside shot to give the U.S. the 11-10 lead with 1:10 remaining.
Gurenlian again won the faceoff, but after his shot attempt sailed out of bounds, Canada called a stick check on Gurenlian and his stick was deemed to be illegal. Canada got possession of the ball and extra man opportunity with 1:01 remaining.
The U.S. man-down defense came up big, denying Canada and sealing the game as Joe Fletcher stripped Matthews of the ball and the U.S. ran out the clock to take control of the Blue Division with a perfect 3-0 record.
