Jake Allen made 38 saves and the Blues used three first-period goals to beat the Dallas Stars 4-2 on Saturday night and spoil coach Ken Hitchcock’s return to St. Louis.
Carl Gunnarsson, Joel Edmundson and Jaden Schwartz each scored in a five-minute span in the first, and Vladimir Tarasenko added a power-play goal in the third.
John Klingberg and Mattias Janmark scored for Dallas. Kari Lehtonen made 17 saves.
The Blues opened the season with a 5-4 overtime win at Pittsburgh on Wednesday. The Stars lost to the Vegas Golden Knights 2-1 on Friday.
Hitchcock coached the Blues for six seasons, going 248-124-41 before being fired last February.
