The Caps spotted Buffalo a 2-0 lead then roared back with a pair of goals in the third to force overtime. But limiting the Sabres to two goals for an eighth straight game wasn't enough, and Buffalo halted its slide at Washington's expense.
After failing on two separate chances to exit their own end safely, the Caps fell down 1-0 just ahead of the five-minute mark of the first. Carl Hagelin's breakout saucer pass for Lars Eller did not connect, and Buffalo's Colin Miller put the puck back down the wall. John Carlson got to it but didn't get much on his bid to chip it out, and Rasmus Dahlin flagged it down neatly. Dahlin went to Marcus Johansson, who put it on a tee for Victor Olofsson. From the right dot, Olofsson put a wrist shot past Holtby for a 1-0 lead at 4:53 of the first.
For the fifth time in 10 games, the Caps had just one power play chance in the game. That didn't come until after they fell behind on Buffalo's first extra-man opportunity of the game, in the first minute of the middle period.
With Brenden Dillon off for slashing, the Sabres won the draw and snapped the puck around their end with flair, ultimately isolating Jack Eichel for a one-timer for the left dot that made it 2-0 just 53 seconds into the second. It was Buffalo's first power-play goal in eight games, ending an 0-for-17 drought.
For the first half of the game, Washington authored plenty of one-and-done or none-and-done visits to the Buffalo end of the rink. Midway through the second period, the Caps started to show some signs of offensive life. Tom Wilson seemed to spark the team on a shift midway through second, where he laid a hit on Johan Larsson in neutral ice and then hurried Jake McCabe into icing the puck. Alex Ovechkin got a good scoring chance off the ensuing faceoff in Buffalo ice, and Wilson himself hit the goalpost later in the shift.
Buffalo goaltender Linus Ullmark stopped the Caps' best scoring chance of the first 40 minutes, blockering aside Nick Jensen's backhand bid from in tight off after a sublime play from Ilya Kovalchuk to set him up.
In the third, the Caps began to tilt the ice, and they were able to solve Ullmark after Evgeny Kuznetsov won a left-dot draw in Sabres territory. Ovechkin pulled the puck out of the pile, dragged it around a Buffalo defender and snapped it past Ullmark to make it a 2-1 game at 3:33.
