Mike Green scored a power-play goal eight minutes into overtime Saturday to give the Washington Capitals a 1-0 victory against the New York Rangers for a 2-0 lead in their Eastern Conference quarterfinal series. Games 3 and 4 are in New York Monday and Wednesday. New York went on a power play early in overtime when Washington's Steve Oleksy took a delay-of-the-game penalty at 1:51, but the Rangers did not get a shot on goal with the extra man. New York's Ryan McDonagh then was whistled for the same infraction at 7:09 and Washington capitalized. Green slapped the winner past New York's Henrik Lundqvist from the blue line, putting New York up against the wall. The Rangers have won only one playoff series in their history after dropping the first two games, that coming in 1996 against Montreal. The teams skated through 68 minutes of taut, tight-checking playoff hockey with New York goalie Lundqvist and Washington's Braden Holtby repeatedly slamming the door on scoring opportunities. Holtby has surrendered just one goal in the first two games. The game marked the Rangers debut for right wing Derek Dorsett, who was acquired from Columbus in an April 3 trade but had broken his clavicle four weeks earlier while still with the Blue Jackets. He had missed 25 games, including 13 with New York. Dorsett took a high-sticking penalty at 15:58 of the first period, and the Capitals had several good chances on the power play but couldn't solve Lundqvist. He finished the scoreless first period with 12 saves while Holtby stopped seven New York shots.
