The Irish entered the tournament unseeded but left a lasting impression on those who follow the sport with their run knocking off three seeded teams and advancing to the title game for the first time in the programs history.
For Duke it was the programs first championship after reaching the title game twice before losing by one goal in each contest.
Notre Dame's Zach Brenneman got the Irish on the board fist with an unassisted score and would post two more scores on the day.
After Brenneman's first score Duke countered with scores from Zach Howell and Steve Schoeffel before Brenneman closed out the first period with his second score on the day tying the score at 2-2.
The second period saw only Schoeffel score for Duke with 1:24 left in the period.
Notre Dame would counter early in the third period as David Early tied the game at three before Howell scored again with 9:30 left in the period.
Brenneman struck again with 1:12 left in the third period and both teams entered the fourth period tied at four.
The Irish struck first in the fourth period as Sean Rogers scored with 11:56 left in the period. Duke would answer a few minutes later as Justin Turri scored with 8:44 remaining in regulation.
While the game lacked high scoring it did provide for lots of excitement as the two teams saw five ties with neither team taking more than a one score advantage. Overall the contest will go down as the lowest scoring championship match in tournament history.
In overtime Duke wasted little time as C.J. Costabile scored with five seconds off the clock giving Duke their first championship in programs history.
Notre Dame finishes the season with a record of 10-7 and continues to build upon the success the program has enjoyed under head coach Kevin Corrigan.
