ST. LOUIS -- The Blues' Brian Elliott made 21 saves as St. Louis tied a franchise record with its 29th home victory of the season.
St. Louis is an NHL-best 29-4-4 at home with four games left. The Blues went 29-7-4 at home in 1980-81. St. Louis, 44-18-7 overall for a league-leading 95 points, has won four in a row and eight of nine.
Elliott, who backed up Jaroslav Halak the last three games, lowered his NHL-best goals-against average to 1.61. The Blues have allowed just one goal in each of the last four games and two or fewer in nine straight.
David Perron, Chris Stewart, T.J. Oshie, and Alex Pietrangelo scored for St. Louis, 36-0-0 when scoring three or more goals. Cam Atkinson scored for Columbus.
