ATLANTA - The Washington Capitals are turning the Southeast Division race into a one-team show.
The Atlanta Thrashers should need no more convincing of the Capitals' dominance.
Mike Knuble and Alexander Semin each scored two goals, and the Capitals beat Atlanta 8-1 on Saturday night for their fifth straight win over the Thrashers, including three this season.
The second-place Thrashers are 16 points behind the Capitals in the division.
"They are a highly skilled team with highly skilled players and those players beat us, no way around it," Atlanta defenceman Ron Hainsey said.
Michal Neuvirth stopped 38 shots in the runaway win.
The Capitals, who scored four goals in the third period, matched their season high for a game. They have scored at least four goals in three straight wins.
The Thrashers ended a nine-game losing streak with a shootout win over the New York Rangers on Thursday night.
The team's continued struggles could make it more difficult to re-sign Ilya Kovalchuk, who was stopped on seven shots.
"This team is having trouble scoring goals," Atlanta coach John Anderson said. "Our big guns, they have to start scoring goals. We have some guys on the team that are underachieving in the scoring category."
The Thrashers have allowed four or more goals in 11 of 13 games. They had not given up more than six before being overwhelmed by the Capitals.
Anderson said the Thrashers "felt sorry for ourselves" in the third period.
"You can't stop playing, no matter what," Anderson said.
Knuble, Semin and Nicklas Backstrom scored in the first period. Knuble pushed the lead to 4-0 with his second goal, on an assist from Alex Ovechkin, early in the second.
"I capitalized on my chances," Knuble said.
Semin, David Steckel, Tom Poti and Jason Chimera completed the rout with goals in the third period.
Maxim Afinogenov scored past a diving Neuvirth 14:14 into the second period for Atlanta's only goal.
Johan Hedberg stopped only five of nine shots before he was pulled early in the second period. Ondrej Pavelec stopped 24 shots in relief.
Washington leads the NHL with an average of 3.51 goals per game. The Capitals almost matched that in the opening 20 minutes. They scored even-strength, power-play and short-handed goals in the first period for a 3-0 lead despite being outshot 18-7.
"It's hard to say you got off to a good start when you are down 3-0, but the start was there," Hainsey said. "We had our chances. We got none and they got three."
The opening period was a confidence-builder for Neuvirth.
"I had a couple of good saves in the first period," he said. "It was a great 20 minutes for us. It gave me a lot of confidence."
While the young goalie's confidence soared, the Thrashers' frustrations showed.
"In the first period, they were working hard," Washington defenceman Brian Pothier said. "In the second, they seemed a little discouraged. The world caved in on them a little bit."
Knuble scored on a deflection to open the scoring. Semin added a short-handed goal before Backstrom's power-play goal with 19 seconds remaining in the frame.
"The lesson learned tonight is that we need to play better," Hedberg said.
