GLENDALE - As soon as Coyotes captain Shane Doan left the ice in the second period, his team's discipline - and possibly the series - left with him.

That discipline has been the cornerstone of the Coyotes' success, and it was challenged the moment the stars of Hollywood arrived in town. The Los Angeles Kings are big and skilled, imposing a physical threat the Coyotes have yet to encounter in the playoffs.

That combination stymied the Coyotes in Game 1 and intimidated them in Game 2. A string of penalties, which included a game misconduct to Doan, unraveled the Coyotes as they fell 4-0 to the Kings on Tuesday night in front of 17,149 at Arena.

L.A. snatched a 2-0 series lead in the Western Conference finals behind Jeff Carter's hat trick.

"It's frustrating not winning, not being able to do the things you want to do," Coyotes coach Dave Tippett said. "It's frustrating."

Despite revamping their lineup, the Coyotes trailed 2-0 by the early part of the second period with the Kings securing goals from Dwight King and Carter.

After that, the Coyotes' frustration peaked.

First, defenseman Keith Yandle was issued a roughing penalty for going after Brad Richardson with about five minutes left in the second.

"I don't know why I was the only one penalized," Yandle said. "It was a guy hitting our goalie, and I got punched. I punched the guy back, and usually they take two, but I guess they needed the power play."

While killing the penalty, Kings center Trevor Lewis had his back turned to the ice as he fished for the puck along the boards.

Doan boarded Lewis, leveling his shoulder into Lewis' numbers, and Doan was handed a five-minute major and a game misconduct.

"He turns. He looks right at me. I didn't even look at him again," Doan said. "I was looking at the puck, because I was trying to poke the puck free. He turns away as I'm coming in."

Even though Lewis suffered only a cut on his nose, the play could be reviewed by the NHL and result in a suspension for Doan. Already this season, Doan has been suspended (three games for elbowing in March) and fined.

Doan's absence gave the Kings' a 5-on-3 advantage, as Daymond Langkow also was assessed a slashing call on the sequence. A minute and a half later, goalie Mike Smith whacked Kings captain Dustin Brown on the back of the legs with the paddle of his stick.

Brown crumbled to the ice but was called for diving, and Smith took a slashing penalty. On that ensuing Kings 5-on-3 power play, Carter tipped a wrist shot from Anze Kopitar to make it 3-0 at 18:49.

The intermission did little to add composure back into the Coyotes' game.

Near the midway point of the third, Martin Hanzal boarded Brown and was tossed from the game, Derek Morris was called for kneeing, and Antoine Vermette was given a 10-minute misconduct for roughing.

Carter sealed the hat trick, burying a rebound at 12:56.

"They took the steam right out of us," Yandle said. "Just weren't able to get back in the game."
