Since 1993, when Harvard last captured a Beanpot Tournament title, it has been Boston College or Boston University winning the championship game, and that will be the case for the 19th straight year.

After No. 1-ranked BU dispatched Harvard in the opening game last night, the Eagles feasted on Northeastern in the nightcap at TD Garden, beating the undermanned Huskies, 7-1.

The most painful aspect of the loss for the Huskies was that BC got two goals from freshman phenom Johnny Gaudreau, who was supposed to play for NU but changed his mind when former coach Greg Cronin signed on with the Toronto Maple Leafs staff.

Northeastern kept it close in the first period, going into the first intermission down by a goal at 2-1.

BC coach Jerry York said his team was fortunate to be ahead after the first. He said his team was able to take advantage of poor ice conditions caused by the back-to-back games.

“There were bouncy pucks,’’ York said. “They were on the power play and we got two shorthanded goals. Sometimes the ice gets rough here and we took it to our advantage. That got us really going. I thought our team came out and played very well in the second and third period.’’

BC took the lead at 5:14, taking advantage of a Huskies turnover, of which there were many.

Gaudreau had an assist on the play. He forced freshman defenseman Josh Manson to cough up the puck and then dropped a pass back for senior right wing Paul Carey, who rifled it past junior goalie Chris Rawlings on a one-timer from the slot that went to the glove side.

At 9:43, Gaudreau potted his first of the evening. It was yet another turnover that cost the Huskies. This time it was sophomore defenseman Luke Eibler who attempted to force a cross-ice pass. Gaudreau collected the puck and sent a low-velocity backhander between Rawlings’s pads for his 10th of the season.

NU got on the board, cashing in on a five-on-three advantage. Nifty freshman left wing Ludwig Karlsson, who is having an impressive season, slid a pass into the right circle for strapping defenseman Anthony Bitetto. The sophomore one-timed a shot from the right circle, beating BC junior goalie Parker Milner to the glove side.

It all went south for the Huskies in the second as the Eagles erupted for three goals, two of which were back-breaking shorthanders.

NU has struggled on the power play all season and surrendering two goals while on the man advantage only rubs salt in that wound.

For coach Jim Madigan, who became the eighth straight first-year coach at Northeastern to lose his opening Beanpot game, the experience was more than a little disappointing.

“They outplayed us, they outcoached us, they wanted it more than us,’’ Madigan said. “They were much more hungry, they were stronger on pucks. Right from the get-go they took it to us and we couldn’t get going. We just didn’t play to their tempo at all. We got schooled today, bad.’’

Bitetto lost the puck at the point and the Eagles took off on a two-on-one break. Senior Barry Almeida raced up the right side with the puck and threw it across the slot to junior right wing Steven Whitney in the left circle. Whitney rapped it past Rawlings for BC’s ninth shorthanded goal of the season.

Gaudreau made it a 4-1 game and not much of a contest when he converted a rebound at 8:58. Junior blueliner Patch Alber fired the puck down from the right point. Rawlings made the initial stop but Gaudreau was there for the rebound.

At 13:11, the Eagles got another shorthanded goal - again by opportunistic Whitney. This time it was junior right wing Justin Daniels who couldn’t corral the puck at the point. Whitney, who was positioned in the right circle, attempted to make a pass down low but Bitetto made a nice play to break it up. However, the puck bounced right back to Whitney, who fired a shot from the right circle that beat Rawlings to the short side, high over the glove to make it 5-1. It was BC’s 10th shorthanded tally of the year, which ties the school with Colgate for tops in the nation.

The Eagles added on at 8:47 of the third with Almeida scoring during a power play on Clay Witt and Carey potted his second with a tip in front at 17:20.

While Harvard and Northeastern will be pondering what might have been when they meet for the consolation game next Monday afternoon, BU and BC will be back on the big stage for the title. For the former two teams, it’s a scenario that has become all too frustrating. For the latter, it is one that has become satisfyingly familiar.
