Blues 3, Senators 2: Vladimir Tarasenko scored his 11th goal in 13 contests and Brian Elliott made 24 saves against his former team as visiting St. Louis returned to its winning ways.

Alex Steen and Maxim Lapierre also tallied for the Blues, who snapped a modest two-game skid and skated to their 11th win in 14 outings. Defenseman Alex Pietrangelo notched a pair of assists while Jori Lehtera and Jaden Schwartz had one apiece for the second straight contest.

Mika Zibanejad scored a power-play goal and captain Erik Karlsson also tallied for the Senators, who dropped to 5-2-3 at home and will open a five-game road trip in Detroit on Monday. Bobby Ryan notched an assist for his sixth point in his last seven outings.

Lapierre made a deft move along the goal line before backhanding the puck past Robin Lehner (30 saves) to open the scoring at 4:16 of the first period. Zibanejad deposited Ryan's centering feed past Elliott from in close with 3:37 remaining in the session, but Tarasenko answered 30 seconds later by wiring a shot from the left circle inside the right post for his team-leading 12th goal.

Steen deflected defenseman Jay Bouwmeester's shot from the point past Lehner to give St. Louis a 3-1 advantage 12:45 into the second. T.J. Oshie failed to convert a short-handed breakaway before Karlsson's seeing-eye shot from the point found its way past a screened Elliott with 4:39 remaining in the session, but Ottawa failed to net the equalizer.
