Kim Martin stopped 28 shots to lead Minnesota Duluth past Wisconsin 4-0 Saturday at the NCAA women's hockey championship.

The win was the school's fourth championship in eight years, and first since 2003. Wisconsin beat UMD 4-1 in the women's Frozen Four final last year for its second straight crown.

Haley Irwin, Emmanuelle Blais, Sara O'Toole and Karine Demeule scored for the Bulldogs (34-4-1), who beat Wisconsin (29-9-3) five out of six times this season.
