Thirteen seconds after a Lightning power play ended, Ovechkin gave the Capitals a 1-0 lead when he got a loose puck in the offensive zone, skated into slot and scored with a wrist shot at 18:51.
"You can tell that he's had a good summer, good training camp," Laviolette said. "Everything was just a little bit off last year. Still had a good year last year, but you can see the jump, and this year, just looks like he's moving better."
Ovechkin appeared to score again 14 seconds later when his shot deflected off Vasilevskiy and across the goal line. The Lightning challenged, and after video review it was ruled Vasilevskiy gloved the puck before it completely crossed the line.
"I think today was an interesting game," Ovechkin said. "We don't give them much, they don't give us much. Overall, I think it was a good game."
Sergachev tied it 1-1 with a one-timer from the left point at 4:23 of the third period off a pass from Stamkos.
