The winning goal came one second after the penalty expired. The Blues outshot the Blackhawks 8-to-6 after twenty minutes of play. The game victor came on a powerplay after Blues captain Alex Pietrangelo flipped a puck out of play drawing a late delay of game penalty towards the end of regulation.

Hossa's goal, his seventh of the season, came off a rebound after goalie Jake Allen stopped the initial shot by defenseman Gustav Forsling but could not corral the rebound. Anisimov had scored eight goals and added nine assists in his last 11 games.
The leading scorer in the NHL, Blackhawks center Artem Anisimov, had to leave the game in the second period because of an upper-body injury. "It's not a good recipe". New linemate Artem Anisimov also tallied to extend his career-high point streak to 11 games, but he was held off the scoresheet in Chicago's 5-2 setback against St. Louis on October 12. He will be re-evaluated in three weeks.
Both teams unveiled their jerseys Wednesday for the January 2 game at Busch Stadium, and both clubs went with throwbacks from a half-century ago. The Blues have hit the goalpost or crossbar 15 times this season, tops in the National Hockey League. The fact that the margin is so close - that a win tonight puts the Blues within a point despite their scoring drought - is more a testament to the decidedly un-Central play of the rest of the teams.
