CHICAGO -- Vladimir Tarasenko scored at 3:54 of a whistle-free overtime to give the St. Louis Blues a 6-5 come-from-behind win over Chicago on Wednesday night, handing the defending champion Blackhawks their first home loss this season.

Tarasenko, who also had an assist, beat Corey Crawford on the glove side from the slot for his seventh goal after taking a nifty behind-the-back centering pass from Alex Pietrangelo.

Alexander Steen scored two goals, and Robby Fabbri, Jay Bouwmeester and David Backes each had a goal and an assist in regulation for St. Louis, which allowed more than three goals for the first time this season.

Patrick Kane, Brent Seabrook, Teuvo Teravainen and Andrew Shaw each had a goal and an assist and Marko Dano -- recalled from the minors on Monday -- got his first goal to help the Blackhawks take a 5-2 lead after one period.

After a sloppy start that saw them fall behind by three in the first period, the Blues roared back tied it at 5-5 in the second on goals by Steen, Bouwmeester and Backes.
