Top-seeded Union College advanced to the NCAA East Regional final by defeating Vermont 5-2 on Friday in Bridgeport, Conn.
The Dutchmen, the nation's top-ranked team and a three-time ECAC tournament champion, will face Providence of Hockey East on Saturday. The Friars defeated Quinnipiac 4-0 in the second game.
Union (29-6-4) got two goals each from Max Novak and Matt Hatch. Mat Bodie also scored, Kevin Sullivan had three assists, and Daniel Carr set up two goals. Union is 13-0-1 in its past 14 games.
Chris McCarthy had both goals for Vermont (20-15-3) of Hockey East, which was making its first NCAA appearance since 2010.
"They're an excellent team, and they took advantage of their opportunities," Vermont coach Kevin Sneddon said.
Providence 4, Quinnipiac 0 -- Goaltender Jon Gillies stopped 37 shots to help Providence win an NCAA tournament game for the first time since 1991.
Mark Jankowski, Anthony Florentino, Shane Lake and Trevor Mingoia scored for the Friars (22-10-6), who scored three second-period goals. Providence is in the tournament for the first time since 2001.
Gillies and Jankowski were selected by the Calgary Flames in the 2012 NHL Draft.
Quinnipiac of the ECAC, which lost to Yale in the championship game last spring, finished the season 24-10-6.
Ferris State 1, Colgate 0; North Dakota 5, Wisconsin 2 -- In Cincinnati, Gerald Mayhew scored a power-play goal midway through the first period, and C.J. Motte made it stand up by stopping 35 shots to propel second-seeded Ferris State into the Midwest Regional final Saturday.
The Bulldogs (29-10-3) of the WCHA posted their sixth shutout of the season, five of them with Motte in goal. Colgate (20-14-5) of the ECAC had more shots on goal but couldn't get one past the junior.
"I think for whatever reason, I was in a groove," Motte said. "I think I brought my A-game this weekend, but that was what we needed to do for everyone."
Ferris State will play North Dakota, which upset top-seeded Wisconsin in the second game.
Mark MacMillan deflected Brendan O'Donnell's shot from the right wing into the net, a goal that was upheld after video, with 1:44 left to break a 2-2 tie. Rocco Grimaldi hit the empty net twice in the final minute.
North Dakota (24-13-3) of the NCHC was the last team to get into the tournament; it received the 16th bid when longtime WCHA rival Wisconsin (24-11-2) beat Ohio State for the Big Ten title.
