For the second time in as many nights, Carlson supplied what would prove to be the game-winning goal in the first period.
Late in the first, Michal Kempny took a penalty for closing his hand on the puck, the Caps' first infraction in 105 minutes and 20 seconds, dating back to the second period of Saturday night's game against the Red Wings in Detroit.
The Caps killed off that carryover minor, but they didn't muster much in the way of offense in the second period. Washington had a couple of shots early and a couple more late, and went without for nearly 13 minutes in between. They also took a couple more penalties, killing them both.
For the second time in his nine starts, Samsonov carried a shutout into the third period. He might have notched his first NHL whitewash on Wednesday, but for one puckhandling miscue that cost him early in the third.
Samsonov went behind the net to stop a Kings dump in, and the puck hopped up his stick as he went back to the crease. Meanwhile, Los Angeles forward Blake Lizotte swiftly skated in and collected it, and he tucked it in on Samsonov, who didn't appear to be fully aware of the danger. Lizotte's goal made it a 2-1 game at a juncture when Washington had managed just three shots on net at 5-on-5 over the previous 29 minutes and change.
Despite their lead being halved, the Caps went on about their business. They drew their only two power plays of the game in the third, but weren't able to convert on either. Although their lead was down to a single goal, they weren't really threatened or tested, nor did they appear to be at all worried about losing the lead they had held since the game's fifth minute.
With Quick off for an extra attacker and just over a minute remaining, Tom Wilson removed any lingering doubt when he sailed a clearing attempt straight into the yawning cage from long distance, cementing the victory for the Caps and allowing the Staples Center patrons to wake up and drive home.
