LAS VEGAS

Alex Ovechkin put both hands to his head and screamed while he left the bench and skated into the thick of the Washington Capitals’ joyous celebration.

And right before Ovechkin hoisted the Stanley Cup, the Washington captain put both hands on his head again in a gesture of disbelieving ecstasy.

You can believe it, Ovi. So can the Washington fans whose championship drought is finally over.

After striving through 13 of his franchise’s 43 seasons, the Russian superstar and the long-suffering Capitals are sitting on top of hockey for the very first time.

“It doesn’t matter what happened before,” Ovechkin said through his gap-toothed grin. “We just won it.”

Lars Eller scored the tiebreaking goal with 7:37 to play, and the Capitals claimed their first NHL title with a 4-3 victory over the Vegas Golden Knights on Thursday night in Game 5 of the Stanley Cup Final.

Ovechkin capped his playoff MVP campaign with an early power-play goal, and Devante Smith-Pelly tied it with a full-stretch goal midway through the final period of the Capitals’ fourth consecutive victory over the Golden Knights.

Vegas’ incredible expansion season finally ended, and so did the Capitals’ wait for a title since their debut in 1974. But after so many years of crushing disappointment for a team with a lengthy history of postseason failure, these Caps confidently won their fourth consecutive closeout game with a tenacious third-period comeback in Vegas.

Ovechkin and his teammates are Washington’s first championship hockey team — and their city’s first champion in a major pro sport since the Redskins won the Super Bowl in early 1992.

After Ovechkin accepted the Conn Smythe Trophy, he received the Cup from NHL Commissioner Gary Bettman. Ovechkin shouted “Yeah! Yeah! Yeah!” before skating away and hoisting the prize over his head for a victory lap in front of thousands of red-clad fans.

When a succession of teammates finally got the Cup back to Ovi, he handed it to Ted Leonsis, the Caps’ owner since 1999.

The Caps couldn’t win a Cup without a little late weirdness, however: The game clock stopped working on the T-Mobile Arena scoreboards during the final minutes, and the Capitals angrily protested while they played on. Vegas never got close to a tying goal despite both teams getting an extra chance to rest while the officials checked on the timing. The clock finally hit zeros, allowing the Caps to storm the ice behind their net for a frenzied celebration.

Reilly Smith scored a goahead goal late in the second period for the Golden Knights, who won seven of their first eight home playoff games before dropping the last two.

The defeat ended the storybook inaugural season of the Golden Knights, who became the NHL’s 31st franchise last fall and immediately launched into arguably the greatest debut in modern pro sports history. Few expected the division title they delivered, and fewer still thought Vegas could challenge for a championship.

Forward T.J. Oshie spent a moment in the celebration looking up for his father, Tim, who he said was recently diagnosed with Alzheimer’s disease.

Washington’s win was its 10th on the road in this postseason, tying the NHL playoff record and illustrating the superior toughness of this team. While past editions of the Caps created their team’s reputation for postseason flops in part by losing five playoff series in which they had won three of the first four games, Ovechkin’s latest group promptly closed out all four of its series this year on the very first try.

The Caps also came back from series deficits in all four rounds and clinched all four series on the road.

The remarkable Golden Knights hadn’t lost four consecutive games in their entire inaugural season before the Caps rolled them.

The Capitals had thousands of fans in the Vegas crowd and a building full of supporters watching back home along with countless thousands outside in the crowded D.C. streets. They got a barn-burner of a finale befitting this thrilling series, with wild shifts of momentum before that bizarre clock incident that didn’t appear to affect the outcome much.

The Capitals’ triumph also adds another chapter to a stretch of sweet relief for long- suffering, loyal sports fans across North America. The NFL’s Philadelphia Eagles won their first Super Bowl in February, and baseball’s Houston Astros won their first World Series last November.

First-time titles are all the rage, and Ovechkin and the Caps have paid their dues for this one.
