DALLAS — Wyatt Johnston scored goals on a ricochet and a roller, Matt Duchene had a tiebreaking power-play goal and an assist, and the Dallas Stars beat the Minnesota Wild 4-2 in Game 2 on Monday night to even their Western Conference first-round playoff series.The Stars went ahead to stay with a power play winding down about four minutes into the penalty-filled second period when Duchene made a quick pass to Mikko Rantanen and then got the puck back just in front of the crease.

I thought they played two, we played one,” Stars coach Glen Gulutzan said. “So it’s more of what we look like, more of the way we are, but you can still see how tight it is.”Jason Robertson, who like Johnston had 45 goals in the regular season, also scored for Dallas.
