ST PETER — For the first time in the nine-year history over the NCAA Division III women’ hockey tournament, a school from the west region is hosting the Frozen Four, as the national semifinals and championship will be played today and Saturday at Gustavus Adolphus’ Don Roberts Ice Rink.

The Gusties have played in three other national-championship weekends and won the third-place game in 2002 and 2005. All of those experiences took place in the eastern region.

“It’s different,” coach Mike Carroll said. “We’re in our own building, the players can go to class and practice at our normal time. ... We’re just going to try to worry about the things we can control.”

Gustavus will play defending national champion Amherst at 7 p.m. today. Norwich and Elmira will open the tournament at 3:30 p.m. today.

The third-place game will take place at 3:30 p.m. on Saturday, and the championship game will start at 7 p.m.

“I expect us to play well this weekend,” Carroll said. “If we weren’t playing our best at the beginning of the season, we’re playing our best at the end.”

A weekend pass costs $20 for adults and $10 for students. Single-session tickets are $12 and $6.
