The Gophers left the ice after the second period laughing.
But 20 minutes later, Michigan State was having the last laugh.
From outshooting the Spartans 31-20 through two periods to collapsing in the third for a 4-2 defeat, the Gophers saw their six-game winning streak and precarious hold on top of the Big Ten Conference crumble Saturday at 3M Arena at Mariucci in front of an announced crowd of 9,661.
"It's awful disappointing," Gophers coach Bob Motzko said. "Kind of a tale of two games. … We couldn't have been any better early and any worse late."
The Gophers (13-11-4, 8-6-4-3 Big Ten) spent not even a full day tied with Ohio State for No. 1 in the conference. Saturday's loss — just the second in their past 10 games, both to Michigan State — dropped the Gophers back into a three-way tie, this time for second place, with Michigan State and Ohio State. Penn State is two points clear in first, though the Gophers and Michigan State have two games in hand with three series left in the regular season.
"The Big Ten's a dogfight this year, so everyone's got to come to play every night," Gophers winger Scott Reedy said. "They made that push there, and we've got to be ready for that."
Reedy helped the Gophers build off their 4-1 win Friday with another fast start, scoring the first goal late in the first period. His line, also including Sammy Walker and Blake McLaughlin, accounted for both the Gophers goals Saturday, totaling five overall and 13 points throughout the weekend.
Michigan State didn't score until its 19th shot, leveling in the second period off a rebound from center Patrick Khodorenko. But the Gophers quickly regained the lead from McLaughlin, scrambling to clean up a shot deflected off Michigan State goaltender John Lethemon.
