Merrill tied it 1-1 at 10:06 of the second period. After the Blues failed to get a puck out at the blue line, defenseman Justin Faulk’s pass went right to Merrill, who shot through traffic from the high slot.
Neighbours’ 20th goal restored the St. Louis lead 2-1 at 12:53 when he slid a rebound past Fleury on the power play. Minnesota unsuccessfully challenged the goal for goaltender interference on Neighbours.
"I thought it was offside originally, maybe that that's what they were challenging for, but when I saw the replay, I was pretty confident it was a goal, yeah," Neighbours said. "... That one was just lucky. It probably would have went in if it didn't hit me, but it hit me in the leg and was kind of just sitting there for me. It's just the benefit of being around the net. Sometimes you get some lucky bounces."
The Wild said they felt they hurt their momentum being on the penalty kill too often. Minnesota was effective short-handed though (6-for-7), including 39 seconds of 5-on-3.
"We had a lot of penalties tonight," Fleury said. "It's tough to get momentum, tough to get chances when you're always defending.
"Guys played well. They played pretty good. They got a good bounce on that goal there. It's tough to get some offense when you're playing on the PK."
Krug scored into an empty net at 19:11 of the third period for the 3-1 final.
"I think for us, in the past, we haven't played well in these games," St. Louis coach Drew Bannister said. "By no means do I think we played our best, but I do think we found a way to win in the end. That's an important game for us, and that's an important two points, and we've got to build momentum off this going onto the road."
