MINNEAPOLIS — With two of the hottest teams in the nation facing off Friday night, something had to give in the battle for first place in the WCHA. That something turned out to be Denver's seven-game winning streak, as well as the seventh-ranked Pioneers' grip on the top spot in the conference standings. Short two defensemen and facing a five-minute Denver power play late in a tie game, No. 1 Minnesota killed the major penalty, then got Ryan Potulny's second goal of the evening to claim a 3-2 win at Mariucci Arena and move into first in the league.
