Duncan Keith scored a power-play goal with 8.5 seconds left and the Chicago Blackhawks beat St. Louis 4-3 on Wednesday night to hurt the Blues' playoff hopes.
Andreas Martinsen, Blake Hillman and Alex DeBrincat also scored, and Jean-Francois Berube made 30 saves. The Blackhawks beat the Blues for the first time in three meetings this season.
Vladimir Tarasenko and Brayden Schenn each had a goal and an assist for the Blues. They have lost four straight to fall a point behind idle Colorado for the second wild-card spot in the Western Conference.
Robert Bortuzzo also scored for the Blues, and Jake Allen made 22 saves in his 14th straight start.
Hillman scored a short-handed goal, his first in the NHL, midway through the second to cut the Blues' lead to 3-2. He is the fifth Blackhawk to score their first career goal this season.
DeBrincat tied it at 3 at 8:30 of the third with an unassisted goal.
Bortuzzo opened the scoring at 4:16 of the first period with his fourth goal of the season.
Martinsen tied it for Chicago at 8:57 with his first goal of the season, firing a wrist shot that trickled between Allen's legs after the Blues failed to clear the puck twice.
Schenn regained the lead for the Blues just 47 seconds into the second period, putting home a rebound from Vince Dunn's shot from the high slot. Schenn's 27th goal is a career high.
Tarasenko made it 3-1 at 5:44 of the second. St. Louis took advantage of a Chicago defensive line change and Schenn sprung Tarasenko for a breakaway.
The teams will meet again Friday night in Chicago.
