University of Nebraska-Omaha running back Kyle Kasperbauer was named MVP of the game after scoring two touchdowns and running for 54 yards on 15 carries.

"We watched them in previous games and knew it would be a tough match," U.S. coach John Mackovic said.

Japan kicker Yosuke Kaneoya missed a chance to win the game with a 34-yard field goal in overtime and Coffin sealed victory on the ensuing possession with his second successful field goal in extra time.

With 2:51 remaining in the fourth quarter, Kasperbauer ran for a 10-yard touchdown to tie the game 17-17.

Kasperbauer scored the first touchdown of the game three minutes into the first quarter on a 9-yard run.

"It was an impressive game," Kasperbauer said. "Both teams played well given the conditions."

The United States was taking part in the tournament for the first time with a team of college players from Divisions I, II and III.
