Blues 2, Kings 1 (OT): Alex Steen scored a power-play goal in regulation and a short-handed tally at 13:26 of overtime as host St. Louis took the opener of its Western Conference first-round series against Los Angeles.

Less than a minute after Blues defenseman Kevin Shattenkirk received a double-minor for high-sticking, Jonathan Quick went behind his net to collect the puck and set up a rush. Steen came rushing in and forced Quick to misplay the puck before grabbing it near the left post and backhanding it into the vacant net.

Shattenkirk notched an assist and Brian Elliott made 28 saves for the fourth-seeded Blues, who had lost eight consecutive meetings with the Kings - including last season's second-round playoff series. St. Louis hosts Game 2 on Thursday.

Justin Williams scored and Quick turned aside 40 shots for fifth-seeded Los Angeles, which went 4-0 in overtime en route to the Stanley Cup championship last year.

Just 42 seconds after the Kings were whistled for too many men on the ice, Shattenkirk knocked down a clearing attempt at the blue line and unleashed a shot from above the right faceoff circle that Quick stopped. The rebound went to Steen, who buried it from the low slot at 9:05 of the first period for his second career playoff goal and a 1-0 lead.

The tally stood up until late in the third. Williams skated into the right circle and fired the puck under the crossbar with 31.6 seconds remaining, knotting the contest.
