ST. LOUIS - Mike Richards scored the go-ahead goal with 2:43 to play, Jonathan Quick made 20 saves and the Los Angeles Kings continued their dominance of St. Louis with a 4-2 win over the Blues on Thursday night.

Tarasenko tied it for the second time when he shoved home a puck that had drifted through Quick at 6:44 of the third period to make it 2-2. The Blues rookie had also knotted the score at 1 when he put his own rebound past Quick at 10:55 of the second period.
Lewis made it 2-1 at 12:49 of the second when he corralled a bouncing pass from Stoll to the right of the Blues' goal and sneaked a backhander past Halak.
