Blues spoil Bruins rally with overtime win
Oshie alertly tapped the puck away from Boston's Carl Soderberg behind the net before chipping it past Tuukka Rask at the left post for the game-winning tally.
The goal was Oshie's 14th of the season and second in as many contests.
Jaden Schwartz scored and set up a goal and Alexander Steen netted his team-leading 28th tally for the Blues, who skated to a 3-2 road shootout victory over Boston on Nov. 21.
Jaroslav Halak turned aside 36 shots and Dmitrij Jaskin notched his first career NHL assist in the win.
David Krejci and Brad Marchand scored 2:08 apart midway through the third period to forge a 2-2 tie.
Rask finished with 24 saves for the Bruins, who lost for the first time in overtime and fell to 7-1-2 in their last 10 games.
Steen's slap shot from the edge of the right circle opened the scoring with 4:12 remaining in the first period.
Schwartz unleashed a wrist shot from the top of the left circle 3:32 into the second, but Krejci answered with a snap shot from the high slot before Marchand netted his 18th goal by converting a sharp-angle bid from along the goal line.
