DETROIT -- The Los Angeles Kings showed their mettle in a big game.
Los Angeles moved into a tie for sixth place in the Western Conference, three points ahead of eighth-place Detroit.
"It's a great feeling for this young group of guys to come in and play the Detroit Red Wings in a significant game that they came out on top in," Los Angeles coach Terry Murray said.
"They're right behind us in the standings, and just to push them a little further down, it definitely makes a difference," Kopitar said. "Hopefully it's going to pay off in the end."
"We had a good chance to gain a couple points on these guys, and after the first 10 minutes we stopped skating," Red Wings captain Nicklas Lidstrom said. "We got outworked. The whole second period it felt like we spent in our zone. They carried most of the game."
Richardson tipped in his seventh goal of the season on Scott Parse's cross-crease pass for the winner.
"Great play by Parse," Murray said. "Simply go to the net and keep your stick on the ice."
Harrold tied it 2-all 6:27 into the third period with a wrist shot from the slot. It was Harrold's first goal.
"Everybody was piled up in front," he said. "There was a lot of net on the left side, so I just floated it in there."
Kopitar put Los Angeles on the board 1:55 into the second period when he put a loose puck in the crease into an empty net for his 20th goal.
"We just kind of threw it on the net, and Richie got the rebound and was able to chip it over him," Kopitar said. "We were there."
The goal was the result of Detroit defenseman Jonathan Ericsson's giveaway in his own zone.
Filppula opened the scoring 5:29 in with his fifth goal. He took a pass from Dan Cleary in the high slot, skated to the bottom of the left circle and beat Quick high on the short side.
Bertuzzi made it 2-0 about 2 minutes later with a 5-on-3 goal. Brian Rafalski's shot from the point deflected in off Bertuzzi's leg for his 15th goal. It was originally credited to Rafalski but changed before the end of the period.
A man was on a conduit above a catwalk for a time at the start of the second period. Almost an entire section of stands in the lower bowl was cleared out when the man was noticed. The man was eventually removed and fans were allowed to come back to their seats. ...
