Chicago’s Patrick Sharp scored twice as the Blackhawks blanked the Wild 3-0 in Game Four of their Western Conference quarterfinal series in St. Paul. Bryan Bickell added a tally midway through the third period for Chicago, which holds a three-games-to-one lead in the best-of-seven series. Corey Crawford posted 25 saves for the shutout victory. Minnesota goalie Josh Harding made five saves in the first period but did not start the second. He gave way to Darcy Kuemper to start the middle period after Harding sustained a left leg injury. Kuemper allowed two goals on 18 shots in defeat for Minnesota. The Blackhawks can close out the series with a win at home in Game Five tomorrow in Chicago. The Blackhawks flew back to the Windy City after last night’s game. Minnesota will depart for Chicago this afternoon.
