BOSTON – History was made on Saturday night – in more ways than one.

For the first time ever, the UMass hockey team shut out Boston University in a 4-0 win over the 11th-ranked Terriers at Agganis Arena.

For the first time this season, the Minutemen (8-6-2) scored three power-play goals, with two coming on a major penalty during the second period. Plus, senior captain Lucas Mercuri dished out a career-high three assists.

And just for good measure, there were five overturned goals due to goaltender interference Saturday, which has to be some sort of record.

Through all that, UMass persevered for a convincing victory against the Terriers (8-6-2) in its penultimate contest before the winter break.

“I've told our beat writers a lot here lately that I like this team. Our record is not where it should be. I do like this team a lot and I thought tonight was a great example,” Minutemen head coach Greg Carvel said. “To come in here and beat a high-quality team, and beat them the way we did, discipline was a big factor, power play was a big factor.”

Sophomore goalie Michael Hrabal picked up his first clean sheet of the year as the Prague, Czechia native turned aside all 32 shots he faced.

“I think it doesn't matter if you win 4-0 or 1-0, it's a win, you get three points,” Hrabal said. “I thought that was the most important thing and we did that.”

The 6-foot-7 tender used every inch of his frame early on, robbing BU's Kamil Bednarik of a sure goal with a left-toe save 90 seconds in.

“He was our backbone all game, credit to him,” Mercuri said on Hrabal. “He's been dialed in the past three or four weeks. He had an awesome game, shut out for him, just super proud of him and all the boys rallied around him today.”

Senior Ryan Lautenbach snapped in the game's first goal at 4:25 of the first period after Terriers goalie Mathieu Caron kicked out a juicy rebound into the right faceoff dot. Lautenbach's second of the year made it 1-0 UMass.

Boston University had its first of two called-back goals minutes after Lautenbach's strike, before a major penalty from Cole Hutson put the Minutemen on its first five-minute power play of the night.

UMass scored on the same play as the Hutson major, but it was overturned after review.

UMass couldn't convert on its first extended PP, but got another chance during the second period on a major cross-checking penalty from BU's Brandon Svobada.

This time, freshman Daniel Jencko and junior transfer Lucas Olvestad found the back of the net, to push the Minutemen's lead to 3-0 after 40 minutes.

Jencko blasted home his second in as many games on a slick set-up from freshman Francesco Dell'Ece at 17:35. Then Olvestad tapped home a loose puck in the Terriers crease following a UMass odd-man opportunity at 19:14.

Two more goals were called back in the middle frame, one on each team.

Compared to the first 40 minutes, the third period was a snooze-fest as junior Kenny Connors added an insurance marker (No. 17s first this year) at 9:20 of the third period, counting as the Minutemen's third man-advantage goal of the night, for the 4-0 final score.

Junior Cole O'Hara appeared to make it 5-0 on a partial breakaway goal in the dying minutes but, once again, it did not stand after a goalie-interference review.

UMass finished 3-for-7 on the power play while BU was 0-for-2.

Saturday's battle also served as the first scoreless game of the Terriers' season.

“Anytime you can plug up the middle in the neutral zone, in your own zone, was a focus-part of the game for sure,” Carvel said. “I think we did a good eliminating their chances, outside of the rush, I think we did a good job.”

These two teams will return for round two in Amherst on Wednesday night at the Mullins Center.
