The Washington Capitals held firm when they were a man down, then won it on Mike Green's latest extra-time winner, topping the visiting Rangers, 1-0, Saturday in overtime to take a 2-0 series lead in the Eastern Conference playoffs.

It's the eighth career overtime goal - and first in the postseason - for the defenseman whose more well-known nickname is "Game Over Green."

"When it gets to overtime and guys start to get the shakes a little bit, he's still calm Mike Green," teammate Karl Alzner said. "So he's able to find those goals."

Braden Holtby made 24 saves for his first career playoff shutout for the Capitals and has stopped 59 of 60 shots in the series. Game 3 is Monday in New York.

Green got his chance because the Capitals' power play - the best in the NHL during the regular season - finally returned to the ice thanks to the rule that sends a player to the box when he "shoots or bats" the puck "directly" over the glass while in his defensive zone.

The Rangers had done a better job staying out of the box after taking too many minors in Game 1, but the officials had no choice when defenseman Ryan McDonagh clearly committed the error about 7 minutes into overtime.

"Just got a little too under it," McDonagh said.
