Tampa Bay cut into that Capitals lead on a Lightning power play exactly four minutes after Oshie's second goal, making it a 2-1 game when Nikita Kucherov went top shelf with the rebound of an Ondrej Palat shot.
Sixteen seconds later, the Lightning tied it up. As he was losing his balance and falling to the ice in the slot, Alex Killorn pulled the trigger and fired. The puck clicked off Caps winger Justin Williams' stick, changing direction just enough to find its way behind Washington goaltender Braden Holtby to make it a 2-2 contest at 16:08.
Neither side was able to generate any offense during a second period in which neither side had any power play opportunities. Both goaltenders were solid when they needed to be, and the Caps needed Holtby to make a big stop on Killorn off a two-on-one chance early in the middle frame.
Sixty-one seconds into the third period, the Caps went back on the power play. Once again, they showed good extra-man fundamentals even though they didn't score during the two-minute span. They did retain the puck in the Tampa Bay zone, and Andre Burakovsky - back in the lineup after a 15-game absence because of a hand injury - spotted Matt Niskanen hopping over the boards and into the zone. Burakovsky put it on a tee for Niskanen, who crushed a shot toward the net. Williams tipped it past Lightning netminder Andrei Vasilevskiy for a 3-2 Washington lead at 3:14 of the third. For Williams, the goal was his 20th of the season, marking the sixth time he has reached that plateau during the course of his NHL career.
