Willie Mitchell’s goal with 5:49 left in regulation led Los Angeles past St. Louis, 3-2, at Scottrade Center.  Mike Richards posted a goal and one assist for the Kings, who have won five of seven.  Anze Kopitar also scored while Jonathan Bernier snagged the win with 23 saves.  Vladimir Sobotka and Alex Steen tallied for the Blues, who have lost two in a row since winning three straight.  Jaroslav Halak allowed three goals on 28 shots in defeat.  LA snapped a 1-1 tie at 4:41 of the third as Andrei Loktionov stole the puck from a Blues checker along the left boards and fed Richards for a successful one-timer from the high slot.  The visitors were unable to extend their lead on a subsequent power play, and the Blues knotted the score when Sobotka managed to slip a shot between Bernier’s pads with 7:32 remaining.  But the Kings responded less than two minutes later when Mitchell’s left-point shot beat Halak cleanly. A pair of former Philadelphia Flyers assisted on the tally — Justin Williams and Simon Gagne — for Mitchell’s first goal of the year.  Halak was pulled with more than a minute left, to no avail.  Steen converted a T.J. Oshie pass just 1:07 into the contest, and the Kings didn’t come up with an equalizer until a power-play chance at the 7:36 mark of the second as Richards dished across the crease for a Kopitar tap-in. 
The St. Louis Blues have placed defenseman Carlo Colaiacovo on injured reserve.  Colaiacovo suffered a hamstring injury in a 4-1 win over Florida on November 17. On the season, he has one goal and five assists in 13 games.  To take his spot on the roster, the team recalled defenseman Cade Fairchild from Peoria of the American Hockey League.
