Caps retake the lead on a PP goal, 2-1

Mara and Brasheer came out of the box after their minors for roughing and Mara headed to the Rangers net to help try and clear the zone. He took his hand off his stick and grabbed a Caps player. It was a very tick-tck call (but one that has been made most of the season to increase scoring in the NHL, you take your hand off your stick, they are going to f*ck you), but I have to wonder how Mara gets called for that, and Brasheer leveling Betts with a late hit is "missed".
Rangers go on the penalty kill without Betts and a bad bounce off a Ranger ends up on the stick of Mike Green. He roofed one over Hank glove side for his first goal of the series, and the Caps take a 2-1 lead.

Caps just took a delay of game penalty on Tom poti, too much to ask for another PP goal?
