TAMPA, Fla. — The expected coronation of Boston College as king of men’s college hockey did not come without a struggle. The top-seeded Eagles were pushed to the limit but outlasted the underdog Ferris State, 4-1, in the Frozen Four title game Saturday night at Tampa Bay Times Forum.

It was the third national championship in the past five years for the Eagles (33-10-1), and their fifth over all. The victory over Ferris State (26-12-5), which plays in N.C.A.A. Division II in every sport but hockey, capped a team-record 19-game winning streak for Boston College.

A spirited, well-played game throughout, the Eagles prevailed in front of a raucous crowd of 18,818, the largest for a first-time Frozen Four host in the 64-year history of the event. In the end, it was the superlative performance of Boston College’s junior goalie Parker Milner, who made 27 saves, including a half-dozen outstanding stops. Milner allowed only two goals on 112 shots in four N.C.A.A. tournament games and was named the most outstanding player of the Frozen Four.

“Our team stayed patient through the first two periods,” Boston College Coach Jerry York said. “We got an incredible goal from Johnny Gaudreau to break open the game. During the course of the game, Parker Milner was once again extremely strong in the net. We knew Ferris State was going to be outstanding. They may not have the name recognition, but they are an excellent club.”
