Columbus' Brian Elliott and Philadelphia's Steve Mason both earned shutouts, but Elliott picked up the win in a shootout as the host Blues edged the Flyers 1-0 on Thursday night.
Elliott made 28 saves through overtime, and Mason stopped 35 shots. T.J. Oshie and Vladimir Tarasenko both scored in the shootout for the Blues, and Elliott stopped both Philadelphia attempts in the tiebreaker.
The Blues, winners of three straight and five of seven, improved to 43-19-5 overall and 24-8-2 at home. St. Louis coach Ken Hitchcock, the former coach of the Flyers, earned his 700th regular-season victory.
Hitchcock is the fourth coach to achieve that milestone.
Elliott record his fourth shutout of the season and 29th in his NHL career, including 20 with the Blues. That tied the franchise record set by his former teammate Jaroslav Halak.
