Boston put a fair amount of rubber on Caps goalie Vitek Vanecek early in the game, with most of the shots coming from distance. But Vanecek was unable to contain the rebound of a Brad Marchand shot from the high slot, enabling Craig Smith to take a whack at it from just above the paint. Vanecek kept that one out, too, but Charlie Coyle was just off the right post to cash in on the third opportunity for a 1-0 Boston lead at 7:28 of the first.
Seconds after the Coyle goal, Vanecek denied Marchand on a breakaway to keep the Caps within one.
The Capitals had a chance to pull even or better when Boston took a pair of penalties in short succession in the back half of the first, leading to a two-man advantage of 66 seconds in length. But Washington's varsity power play, fully assembled - aside from the injured Nicklas Backstrom - for the first time in the preseason was rusty on the execution front. It managed a couple of shots during that stretch, but none during the 5-on-3.
Washington had another opportunity with the extra-man early in the second, but again couldn't muster the equalizer. But the Caps struck twice in a short span just ahead of the midpoint of the middle frame, grabbing a 2-1 lead in the process.
First, Evgeny Kuznetsov scored on a bit of a broken play in front. Kuznetsov and Nick Jensen made an exchange at the left point, and Jensen carried down the wall and below the goal line before feeding Garnet Hathaway, who was just off the left post. Hathaway tried to hit Alex Ovechkin in the slot, but the puck instead caromed to Kuznetsov, who had an easy dunk from the weak side to make it a 1-1 game at 6:09.
Less than a minute later, the Caps took the lead. At the Washington line, Jensen poked the puck away from Taylor Hall, and it went right to Kuznetsov, who quickly sprung Tom Wilson on a breakaway. Wilson did the rest, sliding a backhander through Ullmark at 7:05.
