In the second, McDonald put his own rebound past Backstrom to make it 2-1 at 12:17. Less than two minutes later, Shattenkirk sent a shot from the point through traffic that made it 3-1.
Led by free-agent signees Zach Parise and Ryan Suter, as well as captain Mikko Koivu, the Wild scored four or more goals in six of their last nine games entering Monday and put themselves in the hunt for the Northwest Division title.
But the exciting trio was kept off the board Monday and the rest of the Wild were unable to pick up the slack.

Koivu missed time in the first period after getting hit in the face with Chris Stewart’s stick. ... Wild forward Matt Cullen was injured late in the second period and did not play in the third. ... Jake Allen was assigned to AHL Peoria to make room for Elliott. ... The Blues also announced that the Vancouver Canucks have agreed to buy Peoria Rivermen, pending approval from the AHL.
