Allen's 20th NHL shutout moved him into a tie for second in Blues history with Jaroslav Halak and ended Patrick Kane's 15-game point streak for the Blackhawks. It was the longest streak in the NHL this season.
"I'm just trying to keep the game as simple as I can," Allen said. "I think that's when I'm at my best, and if I go back and look at previous years in the good hockey I'm playing, usually it means that I'm in the right spot and things are going my way and I'm doing the right things. I think it's just feeling pretty confident out there."

The last time Kane was held without a point was Oct. 29 in a 3-0 loss at the Nashville Predators. He had 24 points (11 goals, 13 assists) in the streak.
"It was a good run," Kane said. "I think I kind of see the chances were fading the last few games and that maybe it was going to end here soon, I hadn't really been generating as much as I want to. Try to get a couple days rest here and come back strong against Boston (on Thursday), get things going again."
Jaden Schwartz had a goal and an assist for St. Louis (18-5-6), which has won four straight and is 8-0-2 in the past 10 road games, one from tying the Blues record of 11 (10-0-1) set from Jan. 21-March 4, 2000.
"Yeah, I'm not even sure what the point streak is, but we get up for games," Schwartz said. "Whether it is at home or on the road, we still stick to the same game plan. We don't try switching it up and I think we are just doing a good job of sticking to our systems."
