Midway through Sunday’s Game 2, Niklas Hjalmarsson had blocked four shots.

So had Corey Crawford.

But once again, the Minnesota Wild pushed back and gave the Blackhawks all they could handle down the stretch. And once again, it wasn’t enough.

The Hawks held on (for dear life, at times) for a 4-1 victory over the Wild, holding serve at home and heading to the Twin Cities with a 2-0 series lead in their second-round series. Bryan Bickell had a goal and two assists, including the insurance goal with 2:45 left, scoring on a two-on-one with Marian Hossa one shift after hitting the crossbar. Brandon Saad ended a 19-game scoring drought with a pair of goals, including an empty-netter with 1:23 left.

Bickell, after a dreadful regular season, now has five goals and three assists through eight games this postseason, recapturing the magic from last spring’s Stanley Cup run in which he had nine goals and eight assists through 23 games.

The Hawks took a 1-0 lead midway through the first on Jonathan Toews’ fourth goal of the season. Bickell sprung Marian Hossa for a breakaway with a perfect stretch pass, and while Ilya Bryzgalov made a terrific save on Hossa, he was drawn out of position by the play and Toews beat Mikko Koivu to the rebound for an easy tap-in.

The Wild had just two shots on goal in the first, and just two more halfway through the second period. Then, all of a sudden, they took control of the game, peppering Crawford with 11 shots over the next 10 minutes. Crawford was sharp, and also was fortunate — Nino Niederreiter and Dany Heatley each put the puck behind him, but the puck somehow stayed out both times.

The Hawks clung to the lead until the final minute, when, just after a dreadful power play ended, Saad took a pass from Bickell and ripped a shot from the slot past Bryzgalov for his first goal in 20 games.
