Artem Anisimov scored with 5:20 left in the third period to lift the Chicago Blackhawks over the St. Louis Blues 4-2 on Sunday night for their fourth straight win and ninth in their last 10.
Anisimov beat Jake Allen on the glove side from the right edge of the crease for his 22nd goal after taking a pinpoint cross-ice pass from linemate Artemi Panarin. Tanner Kero added an empty-netter with 2.6 seconds left.
Patrick Kane assisted on Anisimov's winner and scored a power-play goal. Jonathan Toews also had a goal and an assist for surging Chicago, which pulled one point behind first-place Minnesota in the Central Division and Western Conference.
Blackhawks defenseman Duncan Keith had an assist for his 500th NHL point.
Magnus Paajarvi and Alex Pietrangelo scored for the Blues, who played their first game following their bye week and lost their third straight.
The Blues host Edmonton on Tuesday night before a three-game trip against Central Division rivals.
