A pair of St. Louis defensemen turned offensive in a much-needed win for the Blues.
Carlo Colaiacovo and Eric Brewer scored 35 seconds apart in the second period to break a tie and lead the Blues to a 5-2 win over the Ottawa Senators on Friday night.
The Blues (10-5-3) snapped a five-game losing streak and improved to 7-0-1 at home. Ottawa (9-10-1), which had won the previous five meetings between the teams, lost for the fourth time in five games.
Colaiacovo and Brewer capped off a threegoal blitz in 86 seconds that erased an early deficit and gave St. Louis a 3-1 lead.
Ty Conklin made 18 saves to record his first win in St. Louis with the Blues. He had been 0-6 with a 4.45 goals-against average at the Blues' home arena.
Ottawa's Brian Elliott stopped the first 17 shots he faced before St. Louis had its fastest three-goal spurt of the season.
Andy McDonald and Patrik Berglund added insurance goals in the third period. Alex Pietrangelo and David Backes both had two assists to help the Blues improve to 13-0-1 at home, dating to last season.
