BOSTON -- A pair of power play tallies and an empty net goal helped UMass knock off No. 1 Boston University 3-2 on Friday night at Agganis Arena. The win, which was the second for the Mass Attack against a No. 1 team this season, moves the squad to 10-12-5 overall and 6-10-4 in Hockey East action, while the Terriers are now 17-9-1 overall and 13-7-1 in conference play.

Sophomores Joel Hanley and Michael Pereira had multi-point nights for the Minutemen with a goal and an assist apiece as UMass collected its first ever road victory against a No. 1 team and fourth overall. Earlier this season on Nov. 5, the Mass Attack upset then-No. 1 Boston College, 4-2 in Amherst.

The Minutemen were on the board first, scoring 7:14 into the opening period. Conor Allen skated the puck out of the UMass zone and sent a pass ahead to sophomore Troy Power. Power's initial shot was stopped by BU netminder Kieran Milan, but sophomore Branden Gracel swooped in to collect the rebound and beat Milan with a back-hander for the power play tally.

Just two minutes later, the Terriers came up with the equalizer. Alex Chiasson fed Matt Nieto from the corner and when Nieto attempted to jam the puck home, it squirted under Kevin Boyle. Chris Connolly tapped it home in the crease to level the score at 1-1 at the 9:31 mark.

The Minutemen added another power play goal to regain the lead 12:47 into the second. Senior T.J. Syner sent the puck towards the net for Pereira, who had his initial shot stopped, but Hanley crashed the net to clean up the rebound to extend his point-scoring streak to four consecutive games.

Then late in the third with Milan pulled, Pereira added the empty net goal at 19:05 off a feed from Hanley to bring the score to 3-1. The Terriers added the final goal on a scramble with five seconds to play as Chiasson scored from Garrett Noonan and Nieto.

Boyle (6-4-4) made 33 saves for UMass, while Milan (15-9-1) finished with 34 stops for BU. The Mass Attack finished with a 37-35 shot advantage and was 2-for-6 on the power play.
