The Eagles (11-4-2, 6-1-1 Hockey East) avoided what head coach Jerry York called "Christmas hockey" -- sluggish play after the long holiday break -- and came out firing.
Three first-period goals put Bowling Green on the ropes, and Boston College cruised the rest of the way to punch its ticket to the final, where the Eagles will face Penn State, which edged host Robert Morris. Bowling Green and the Colonials will meet in the consolation game this afternoon.
Boston College forward Johnny Gaudreau, whom Bowling Green coach Chris Bergerson called "an all-world type of college player," opened the scoring with a beautiful backhand just 1:19 into the game.
Gaudreau picked up assists on the next two goals by defensemen Travis Jeke and Teddy Doherty and extended his point streak to 12 games.
He has 22 points (11 goals, 11 assists) in the past 12 games.
The Eagles' final four goals all were scored by defensemen.
Scott Savage extended the lead to 4-0 with a goal midway through the second period, and Michael Matheson closed the scoring with just 16.3 seconds left in the game.
Jeke, a Pittsburgh native, had a goal and an assist in his first start this season. He earned extra playing time because two of his fellow defensemen are in Sweden for the World Junior Championships.
Boston College goalie Brian Billett, a junior, made 27 saves to earn the first shutout of his career.
