At 1:10 of the third period, Tom Wilson scored on a deflection of Ovechkin's shot from the right circle to give the Capitals a 4-3 lead. Ryan Reaves tied it on a goal from in front 1:31 later.
"We didn't play our best game," Ovechkin said. "I think we didn't execute the puck in the neutral zone at some points. But we're going to watch the video, we're going to watch the highlights and we're going to correct our mistakes and we're going to be better."
Ovechkin finished with one assist, two shots on goal (each in the first period), four hits and a blocked shot in 19:09 of ice time.
"I think next game is going to be different and all the nervousness, all the bad things go away in this game," he said. "We just have to forget about it and bounce back in the next one."
Ovechkin's nerves and excitement were understandable. He's waited 13 seasons to reach this point. But to Capitals coach Barry Trotz, Ovechkin wasn't alone in that regard.
"It was the first experience for some guys in this building against [the Golden Knights]," Trotz said. "I'm confident we have another level. To me, that's exciting."
