DALLAS (CBSDFW.COM/AP) — Jaden Schwartz and Sammy Blais scored in a 33-second span of the third period for St. Louis that knocked Dallas goaltender Ben Bishop out of the game, and the Blues beat the Stars 4-1 on Sunday to force Game 7 in the second-round Western Conference semifinal series.

Schwartz scored to make it 3-1 with 13:23 left when he redirected Alexander Steen’s shot. Steen had gathered the puck outside the right circle after Colton Parayko’s shot deflected off Bishop’s left shoulder and knocked the stunned goalie to the ice.

Bishop was tended to by a trainer and initially stayed in the game, but a switch was made soon after when Blais, playing his first postseason game, got a slap shot past him.

Alex Pietrangelo, their captain, scored only 63 second into the game and David Perron also had a goal for the Blues, who will be on home ice for the deciding game Tuesday night.

The Central Division rivals also went to a Game 7 when they met in the second round three years ago. That series finale was played in Dallas, where the Blues scored three times in the first period and went on to a 6-1 win.

St. Louis rookie goalie Jordan Binnington stopped 22 shots, allowing only a power play goal to Tyler Seguin in the first period.

Bishop, who came into the game with a .936 save percentage in the playoffs, stopped 16 of 20 shots. Anton Khodobin had five saves in the final 12 minutes in his first action this postseason.

The two quick goals by St. Louis came right after Dallas couldn’t score with Binnington sprawled on the ice.

Perron put the Blues ahead to stay at 2-1 when he reached around defenseman John Klingberg to score in what was otherwise a somewhat pedestrian second period.

Oskar Sundqvist skated deep into the right circle and passed back across the front of net. Perron, with Klingberg between him and Bishop, reached his stick around the defender to poke the puck in for his third goal of the playoffs.

The Stars’ 23 shots matched their fewest in the playoffs. Their goal came with 8:25 left in the first period when Mats Zuccarello made a pass from the top of the right circle and Seguin’s shot got under Binnington and trickled past the line to make it 1-1.

The decisive Game 7 will be played in St. Louis on Tuesday night.
