Blackhawks beat Blues in overtime

CHICAGO -- Jonathan Toews scored on a low shot from the left circle at 3:19 of overtime to give Chicago a 4-3 victory over the St. Louis Blues on Wednesday night and move the Blackhawks within two points of clinching a playoff spot in the Western Conference.

Toews beat Ty Conklin on the short side after taking a long lead pass from Duncan Keith and racing in with Blues defenseman Carlo Colaiacovo in close pursuit.

Chicago's Marian Hossa, Tomas Kopecky and Nick Leddy scored in the second period to help the defending Stanley Cup champion Blackhawks erase a two-goal deficit.

St. Louis' Chris Stewart scored midway through the third to set up overtime. T.J. Oshie had a goal and an assist, and David Backes also scored for the Blues, who are out of the playoffs for the second straight season.

Backes' goal was his 31st, matching his career high set in 2008-09.

The Blackhawks, 3-3-1 in their last seven, have two games remaining with Detroit. Patrick Sharp, Chicago's leading goal scorer with 34, returned after missing seven games because of an injured left knee.

He assisted on Hossa's goal at 7:52 of the second that cut the Blues' lead to 2-1 -- and got the Blackhawks' offense rolling. The goal withstood a six-minute video review.

Sharp flipped a centering pass into the crease that deflected into the net off Hossa's left skate. It also wasn't clear if the puck completely crossed the goal line before Conklin swept it out.
