What a difference a week and a half has made.

On April 1, the Blues visited Minnesota on a three-game losing streak and sitting in the No. 9 spot in the Western Conference. The Wild had won eight of their last nine games and were tied for No. 3. On that night, goaltender Jaroslav Halak went down with a groin injury and a struggling Brian Elliott relieved him.

In their return trip to Minnesota on Thursday, the Blues were toting a five-game winning streak, while the Wild were 1-4 over the same stretch, and Elliott had resurrected himself with four straight victories, including back-to-back shutouts.

Make it a six-pack for the Blues and a three-peat for Elliott. The trends continued at Xcel Energy Center, where the visitors stuck to their stingy ways in a 2-0 win over the slumping Wild.

“Chemistry is that elusive animal that you try to catch up to, and when you’ve got it, it feels like you’re never going to lose and when you don’t have it, it feels like you’re never going to win,” Blues coach Ken Hitchcock said. “We’ve gone through a lot of adversity this year, some of it self-prescribed and we’ve come out fighting for each other.”

The six-game winning streak includes five straight wins on the road, which also is the longest current streak. The club will wrap up its four-game road trip tonight against Columbus at Nationwide Arena.

Two creative assists led to goals by Roman Polak and Andy McDonald, allowing the Blues’ offense to break through the one-goal barrier for the first time in its last three games.

McDonald’s third-period goal gave the club some much-needed breathing room, but as it turned out they only needed one, as the story once again was the puck staying out of the Blues’ net.

For the second time in as many seasons, Elliott has a pitched three straight shutouts, and with this trifecta, he has stretched his personal shutout streak to 189 minutes, 29 seconds. The Blues’ overall shutout streak is at 201:24.

“You try not to think about that too much,” Elliott said. “Obviously getting two goals definitely helps the mindset a little bit. But again, we have a different hero every night, with (Polak) getting that goal. He was just talking about getting some goals in his sticks from his equipment rep today, so he got one and it’s good to see.”
