The final equalizer came with eight minutes to play, as a shot from sophomore defenseman Danny Fick was deflected in by O’Regan.

For the first time, Harvard held its ground, not surrendering another score the rest of the way. UMass killed a power play resulting from a third Kiley penalty, and regulation ended with the score knotted at four.

Sheary crashed into Michalek early in the overtime period to give Harvard a five-on-four advantage, but the Crimson couldn’t capitalize. Everson was rejected at the right post by Boyle, denying his bid for a hat trick.

Fallstrom was later turned away on a wrap-around shot, and the Harvard odd-man rush in the waning seconds of the game came up empty as Ford’s shot went high. With either team unable to break the stalemate, the game ended in a deadlock.

The tie continues a pattern of comebacks for the Crimson. In its six wins and ties, Harvard has trailed five times, including in a 7-6 win over the University of New Hampshire in which they fell behind, 4-0, after the first period.

“I think it speaks to the team’s mental toughness,” Ford said. “When things haven’t gone right for us this year, we’ve consistently been able to get back to playing the way we want.”

Harvard was also adjusting to playing its first game of the year on Olympic-sized ice.

“That was a little different. It was a little bit of an adjustment in the first period,” Ford said. “But we settled down.”

McNally’s three assists were a career-high, giving the freshman seven on the year. That total is topped only by Biega, whose two assists give him 10 on the season, tied for fourth best in the ECAC.
