David Perron scored twice as St. Louis switched up its line combinations, Jordan Binnington made 30 saves and the Blues beat the Colorado Avalanche 4-1 on Thursday night to tie their second-round series at a game each.

Jordan Kyrou added a goal and Brandon Saad sealed it with an empty-netter for the Blues as they rode another stellar performance from Binnington. The Blues goaltender stopped 51 shots during a 3-2 overtime loss in Game 1.

Binnington’s flashing his 2019 form, when as a rookie he led the Blues to a Stanley Cup title with a 16-10 mark and a 2.46 goals-against average.

Gabriel Landeskog scored on a power play early in the third for Colorado to make it 2-1. But Perron answered right back with his seventh goal of these playoffs.

Darcy Kuemper stopped 28 shots. Two of the goals he allowed were redirected off the stick of a defenseman.

Nathan MacKinnon and the Avalanche found open ice a scarce commodity against a physical, hard-checking and more determined Blues squad.

Game 3 is Saturday in St. Louis.
