LAS VEGAS — Alex Ovechkin, Braden Holtby and the Capitals stayed cool in the 100-degree Vegas heat and evened the Stanley Cup Final.

Holtby made 37 saves, Ovechkin scored a power-play goal and Lars Eller added a goal and two assists in the Capitals’ 3-2 victory over the Golden Knights in Game 2 on Wednesday night.

The Caps hung on through a scoreless third period for their first Stanley Cup Final victory in franchise history largely because of a bounce-back performance by Holtby, who was battered in the Knights’ 6-4 series-opening win.

Holtby capped his energetic performance with a jaw-dropping stick save with 1:59 to play, stretching back to rob Alex Tuch of a possible tying goal.

“We refocus and pick each other up and that’s a sign of a good team,” Holtby said. “That’s one of our strengths.”

Brooks Orpik ended a personal 220-game drought with the eventual winning goal for the Caps, who rebounded from a ramshackle loss in the opener and handed the expansion Golden Knights only their second home defeat — the first in regulation — in nine postseason games.

James Neal and Shea Theodore scored and Marc-Andre Fleury stopped 23 shots for the upstart Knights, who couldn’t summon their usual clutch magic in the third period, even with lengthy man advantages.

The Capitals lost leading scorer Evgeny Kuznetsov to an upper-body injury in the first period after a big hit from Golden Knights defenseman Brayden McNabb. The Caps avoided any hotheaded retaliation and concentrated on a gritty effort that was enough to even the series.

Game 3 is Saturday night in Washington.

The Caps are just 4-5 at home in the postseason, but they’ll ride a wave of momentum after going into the Golden Knights’ daunting home arena and taking away home-ice advantage in their first Stanley Cup Final in 20 years.

The Caps improved to 9-3 on the road in the postseason after two games in this frequently chaotic series. The first two games of the Stanley Cup Final were split for only the third time in the last 13 editions of the NHL’s final round.

After a rough opener in Vegas, Holtby rounded back into something approaching his form in back-to-back shutouts to close the Eastern Conference finals. While his save on Tuch was the most impressive, he kept the Caps in charge with 15 saves in the third period, including a tenacious effort during a 5-on-3 advantage for 1:09 for the Knights.

“We played smart. We played hard,” Ovechkin said. “Holtby made unbelievable saves.”
