Ryan O’Reilly opened the scoring with a wraparound goal 43 seconds into the action and then pounded in the rebound of Alex Pietrangelo’s hard shot that caught Tuukka Rask up high midway through the third period to snap a 2-2 tie,
After O’Reilly’s opening salvo, the Bruins countered at 13:14 on Charlie Coyle’s rebound goal.
St. Louis took back the lead 2:16 later when Vladimir Tarasenko cruised down the middle of the slot to convert the rebound of Pietrangelo’s low wrister.
Brandon Carlo tracked down the rebound of Patrice Bergeron’s initial shot from the left and fired it off the glove of Jordan Binnington to forge a tie at twos with 5:41 left in the middle frame. The goal was the first of Carlo’s career in the postseason.
Brayden Schenn, who drew the secondary assist on Tarasenko’s 11th of the playoffs, clinched it with an empty-netter from center ice with 1:29 remaining in regulation.
Binnington stopped 21 shots to match Rask with 14 postseason wins. The much busier Tuukka finished with 34 saves.
Game 5 will be in Boston at TD Garden on Thursday night.
