WASHINGTON – Alex Ovechkin scored twice to help Washington overcome an early three-goal deficit, and Chris Clark netted the winner in overtime, leading the Capitals to a 4-3 victory over the Ottawa Senators on Monday night.

Ovechkin scored a power-play goal with 24.4 seconds left in regulation to tie it. Ottawa defenseman Chris Phillips was whistled for tripping with 1:03 to play and the visitors clinging to a 3-2 lead.

Clark then scored 1:33 into the extra period off an assist from Alexander Semin, who also assisted on both of Ovechkin’s goals. The reigning Calder Trophy winner as the league’s top rookie redirected a shot by Semin 7:56 into the second period to cut Washington’s deficit to one goal.

Ottawa led 3-0 less than 12 minutes into the game, chasing Washington goalie Olie Kolzig after only five shots.

Dany Heatley and Antoine Vermette also scored and Andrej Meszaros had two assists in that spurt, which prompted Washington coach Glen Hanlon to call timeout and yank Kolzig, replacing him with backup Brent Johnson.

Lightning 5, Islanders 1

UNIONDALE, N.Y. – Childhood friends Martin St. Louis and Eric Perrin teamed up for the tiebreaking power-play goal in the second period that sent the Tampa Bay Lightning to a slump-busting 5-1 victory over the New York Islanders.

Perrin added another goal in the third period, and Filip Kuba scored twice as the Lightning scored five goals for the third straight game.

St. Louis stretched his point streak to nine games when he fired in a hard shot off a feed from Perrin that gave Tampa Bay a 2-1 lead with 7:12 left in the middle period. The pair, who grew up in Laval, Quebec, went on to star together at the University of Vermont but had never combined on an NHL goal.
