Defenseman Robert Bortuzzo scored his first career postseason goal late in the second period that helped the Blues overcome another big game from San Jose's Logan Couture with a 4-2 victory over the Sharks on Monday night that tied the Western Conference final at one game apiece.

Jaden Schwartz, Vince Dunn and Oskar Sundqvist also scored and Jordan Binnington made 23 saves to send the Blues home for Game 3 on Wednesday night tied in the series.

Couture scored his goals in a span of 1:59, giving him an NHL-leading 13 this postseason but the Sharks couldn't get anything else and lost their third straight Game 2 after winning the series opener. Martin Jones made 21 saves.

The Blues then answered late in the period with thanks to Bortuzzo. He passed the puck from the point to Tyler Bozak and skated in behind Joe Thornton. He then took a pass from Joel Edmundson and beat Jones with a backhander into the top corner for his first goal in 31 playoff games.

Bortuzzo added a big blocked shot in the third when Kevin Labanc got a pass in the slot with time to shoot, negating one of the few good chances San Jose had in the third. The Blues then killed off a power play later in the period before getting the insurance goal with 3:08 remaining when Alexander Steen fed Sundqvist on a rush for the goal that made it 4-2.
