Notre Dame finished the season 17-1-6 to give 68-year-old coach Bobby Clark his first title in 27 years of coaching at Dartmouth, Stanford and Notre Dame.
Patrick Mullins, the nation’s leading scorer, scored for Maryland (17-4-5). The Terrapins were trying to win their fourth national championship and third under coach Sasho Cirovski.
Harrison Shipp, a finalist for the MAC Hermann Trophy as the nation’s best player, set up O’Malley’s winning goal with a perfectly placed free kick in the 60th minute. O’Malley leaped for Shipp’s kick and directed a header past goalkeeper Zack Steffen’s outstretched arms.
Brown tied it at 1 in the 40th minute with a tough-angle shot. He entered the game as a reserve when Vince Cicciarelli was forced to leave with an injury in the 10th minute.
Mullins, Maryland’s own Hermann Trophy finalist, opened the scoring for the Terrapins in the 35th minute.
Moments earlier, Mullins thought a penalty kick was warranted when his shot was cleared off the goal line by what looked to be the arm of Notre Dame’s Patrick Hodan. But Hodan was not called for the hand ball and Mullins was able to collect the rebound and deposit a shot past goalkeeper Patrick Wall.
