Washington downed the Vegas Golden Knights 4-3 on Thursday to take the Cup final in five games.
After the Caps lost the lead and trailed the Vegas Golden Knights 3-2, Washington fought back in the third period, and Eller scored a spectacular go-ahead goal at the 12:23 mark to hand his team the lead and its first Stanley Cup.
Lars Eller scored the go-ahead goal for Washington with 7:37 remaining. The Caps lead the best of seven series three games to one. After so many years of postseason flops and crushing disappointment, these Capitals won their fourth consecutive closeout game with a tenacious third-period comeback.
Both teams came out aggressive in Game 5, but remained scoreless in the first period.
The Capitals had not advanced beyond the second round of the playoffs since the 1998 Cup final when they were swept by Detroit, but defeated Columbus, arch-rival Pittsburgh, and Tampa Bay before downing expansion Vegas this spring.
Vegas' Brayden McNabb took a penalty just 11 seconds later, and Ovechkin set up in his customary spot in the left faceoff circle to put Nicklas Backstrom's cross-ice pass into a sliver of open net. It was Ovechkin's franchise-record 15th goal of the postseason. The Capitals challenged for goalie interference, but the goal was upheld after video review when it was ruled that Djoos caused Perron to contact Holtby before the puck crossed the goal line. Time for him to turn it around one more time at home. Alex Ovechkin, one of the game's premier players who has never won a Cup, has four points in the series.
If Vegas wins and avoids elimination, the Capitals will host Game 6 on Sunday.
