A minute after completing that second kill, the Flames took a 1-0 lead. Brett Kulak took what appeared to be an innocent looking floater of a shot from center point. But Micheal Ferland got a stick on the puck, redirecting it behind Grubauer at 2:08 of the second period.
The Capitals had some scoring chances, but the good ones were too few and far between. While the Caps' infrequent chances were scattered here and there, the Flames were able to sustain more offensive zone time than the weary Caps.
Washington persisted, and the Caps were able to pull even on a significant break when a Calgary clearing bid hit an official and stayed in the Flames' zone. T.J. Oshie scooped up the puck and fed Jakub Vrana, whose shot from the left circle just bled thru Flames goaltender Mike Smith, barely getting over the line to make it a 1-1 game at 4:19 of the third.
Grubauer made yet another huge save soon after Vrana's tying tally. Calgary managed a four-on-one rush, and Flames captain Mark Giordano tried to finish from in tight, from the middle of the ice. But Grubauer flashed the glove to deny him.
Washington wasn't able to successfully manage the late stages of the game. At the end of a long shift, Caps defenseman Dmitry Orlov carried out of his own end and tried to juke his way past a defender at the Calgary line. But Giordano poke-checked Orlov, sending Johnny Gaudreau on a two-on-one rush in the other direction as the Caps chased to catch up. Gaudreau pulled up and waited, and Monahan went to the back door for a sharp feed and an easy tap-in at 9:09.
Just over a minute later, Caps center Lars Eller took an offensive zone slashing call, Washington's first penalty of the night. The Caps killed it off, but it also cost them a couple minutes of precious time. With 2:34 left, Washington was guilty of having too many men on the ice, and that was basically the game. Calgary's power play snapped the puck around the Washington end for most of the ensuing man advantage, whittling time off the clock. The Flames prevailed, ending a four-game home ice skid during which they'd been outscored by a combined total of 14-4.
