Ovechkin scored on a power play 4:26 into the game when he took a pass from Mike Green in the left circle and one-timed the puck past Lehtonen.

The assist was Seguin's first for Dallas, which acquired him from the Boston Bruins in an offseason trade.
After a slow start, the Stars finished the first period with a 9-8 advantage in shots.
The Capitals had some near misses in the second period. Despite putting 13 shots on goal to Dallas' five, Washington gave up the period's only goal.
Washington appeared to have a goal with 12 minutes left in the period, when the puck popped up behind Lehtonen. Nicklas Backstrom pushed the goalie, knocking the puck into the net. The play was ruled no goal on review because of goaltender interference.
A slap shot by Ovechkin squeezed past Lehtonen, but Brenden Dillon tipped the puck away from the net. The goalie appeared to be screened on John Erskine's shot from the left point that hit the right post.
NOTES: Dallas center Rich Peverley, acquired with Seguin in July, made his Stars debut. Peverley missed the preseason after being diagnosed with an irregular heartbeat. Peverley missed a chance for a power-play goal in the third period. He poked a rebound behind Holtby but off the left post. ... Capitals wing Joel Ward found himself unable to open the door of a men's room stall at the team hotel Saturday morning. He tweeted, "Stuck in the washroom ... someone help?" According to the Washington Post, teammates Karl Alzner and John Carlson found a ladder and helped Ward climb over the top of the door.
