Brian Elliott made 44 saves and the Blues scored two, third period goals to come back and beat the Blackhawks 3-2. St. Louis grabs a 2-1 series lead with Game 4 set for Tuesday night in Chicago.
Jaden Schwartz scored 13:32 into the third period with Patrick Kane in the penalty box for double minor high-sticking. There was still 2:29 left on the penalty when Schwarz scored, giving the Blues an additional two minutes with the man advantage.
Patrik Berglund tied the game earlier on a shot that deflected of defenseman Michael Roszival past Corey Crawford.
“We’ve got home ice back again,” Blues coach Ken Hitchcock said. “To me, that’s the whole thing. We’ve got to find a way to keep it now.”
