Making his first appearance in net since Jan. 14, Badger junior Brian Elliott made 25 saves and gave up four goals.
Wisconsin (21-7-3 overall, 15-6-3 Western Collegiate Hockey Association) outshot Michigan Tech 48-29, including 6-0 in the overtime session, and finished the weekend series with 112 shots on goal.
Special teams figured prominently in the outcome Saturday. UW finished 1 of 5 on the power play, but also picked up a short-handed goal. Michigan Tech was 2 of 6 on the power play, with one of its four goals being scored on a 5-on-3 advantage.
Sophomore forward Joe Pavelski led the Badgers with a goal and an assist, giving him two goals and three assists on the weekend. His assist came on a goal from senior defenseman Tom Gilbert, who, for the second straight night, scored the opening goal on a power play, this time with 9:49 left in the first period. Junior forward Robbie Earl provided the other assist.
After a Michigan Tech goal late in the first period, freshman forward Jack Skille scored his ninth goal of the season with help from junior forward Ross Carlson and sophomore defenseman Kyle Klubertanz.
Michigan Tech (7-20-5, 6-13-5) made it 3-2 just a few minutes later but 8:43 into the second, Pavelski scored a shorthanded goal on an assist from senior captain Adam Burish.
The Badgers carried that 4-2 advantage into the third period, but two late Husky goals sent the game into overtime.
Senior forward Nick Anderson, junior center Tyler Skworchinski, senior center Taggart Desmet and senior defenseman John Scott all scored goals for the Huskies. Appropriately, Michigan Tech was celebrating senior night in its final home game of the season.
In net, Husky freshman goalie Michael-Lee Teslak collected 44 saves.
The Badgers played through much of the game without assistant captain center Andrew Joudrey, who was injured on a knee-to-knee collision in the second period.
Minnesota defeated Denver 5-1 Saturday night to complete a series sweep, giving the Gophers a two-point lead over Wisconsin in the WCHA standings. Denver sits one point behind Wisconsin for second place after leaving the Twin Cities empty-handed.
