Mat Bodie and Mike Vecchione also scored and Colin Stevens made 34 saves for Union, the small, liberal arts college from Schenectady, N.Y.

Johnny Gaudreau, Steve Santini, Ryan Fitzgerald and Patrick Brown scored for Boston College (28-8-4).

Ciampini broke a 2-2 tie on a power play at 6:31 of the third period, tipping in Shayne Gostisbehere's one-timer from the point.

Only 18 seconds later, Union's Matt Hatch was given a major penalty and game misconduct for checking Scott Savage from behind into the boards, giving Boston College a 5-minute power play.

The Eagles failed to score, and Vecchione gave Union a two-goal advantage with 8:07 left off a rebound after goalie Thatcher Demko stopped Kevin Sullivan on a breakaway attempt.

With Demko off for an extra attacker, Fitzgerald cut it 4-3 with 1:45 to go. Ciampini restored the two-goal margin with an empty-net goal with 1:09 left, and Brown completed the scoring on a power play with 4.2 seconds to go.

Union improved to 21-1-1 when it scores at least four goals.

Gaudreau put the Eagles on the board less than 4 minutes into the first period, scoring on a rebound in the crease off Kevin Hayes' initial shot for his NCAA-leading 36th goal.

Union tied it on Bodie's slap shot from the top of the right circle 2:39 into the second. Eight minutes later, Ciampini put back a quick rebound off a faceoff win to give Union a 2-1 lead.

Santini countered for Boston College with 4:07 left in the second.
