Berglund's team-leading 12th goal of the season came after the Blues rallied from two goals down in the third period. Sobotka, who is riding the best streak of his career, had both scores to tie it before Berglund's game-winner.
Scott Gomez had a goal and assist for San Jose, which has lost nine of its last 11 against St. Louis.
When we started our journey we made a commitment to our fans to be relevant and to see the Chicago Blackhawks become the best professional hockey organization. There are not two finer symbols of that than Jonathan Toews and Patrick Kane. The commitment we have made to these incredible young men is equal to the commitment they have made to our team, our fans, our entire organization and the city of Chicago.
