TAMPA, Fla. (AP) _ Ulf Dahlen had two goals and an assist and the Washington Capitals won their season-high fifth straight game, 6-3 over the Tampa Bay Lightning Monday.

Dahlen's second goal, with 7:33 left in the third period, put the Capitals ahead 5-3. Dahlen and Jeff Halpern had second-period power-play goals as Washington improved to 7-1-2 in its past 10 games.

Washington's Sergei Gonchar had a goal and two assists. He has six goals and 10 points in the past seven games.

Chris Simon had an empty net goal, and Richard Zednik, who scored both goals in the Capitals' 2-1 win Sunday over the Ottawa Senators, had the other Washington goal.

Darcy Tucker, Chris McAlpine and Steve Martins had the Tampa Bay goals. The Lightning are 1-12-2 over the past 15 games.

Zednik scored the only first-period goal with 15.2 seconds left. Tampa Bay had only one shot in the opening 11 minutes, and the Capitals went 10 minutes without a shot.

The Lightning tied the score 1-1 on a power-play goal by Tucker four minutes into the second period.

After goals by Dahlen at 7:31 and Halpern at 14:41 put the Capitals up 3-1, McAlpine cut the deficit to one at 17:26 of the second period.

Gonchar and Martins traded goals early in the third period before Dahlen made it a two-goal game.

Jan Bullis had three assists for Washington.

Tampa Bay all-star defenseman Petr Svoboba left the game in the second period with a shoulder injury and did not return.

The Capitals were without wing Peter Bondra, who is day-to-day with a knee sprain.
