The St. Louis Blues are in the 2019 NHL playoffs. They could have clinched without even playing if certain results went the way they needed to. Those results just did not go that way, so the Blues are still without an x next to their name.
However, we all know they are getting in. If they win one more game, they are pretty much assured of playing in the postseason. The remaining games in the 2018-19 season are pretty much just to figure out where the Blues will finish.
St. Louis still has a chance to finish first in the Central Division.
