The Denver Nuggets launched their first NBA Finals campaign in franchise history with a dominant 104-93 victory over the Miami Heat on Thursday, propelled by yet another Nikola Jokic triple-double.

Two-time Most Valuable Player Jokic scored 27 points with 10 rebounds and 14 assists to lead the Nuggets, who will try to double their advantage in the best-of-seven series when they host game two on Sunday.

Jamal Murray scored 16 points, handed out 10 assists and grabbed six rebounds for the Nuggets, who led by 24 points in the third quarter and repelled the resilient Heat's fourth-quarter challenge.

"We respect their team a lot," Jokic said. "We just wanted to get the first punch.

"In the first three rounds they won their first game when they traveled on the road and we didn't want to have that to happen. I think we did a good job."

Bam Adebayo scored 26 points to lead Miami. Gabe Vincent added 19 and Haywood Highsmith scored 18 off the bench, but Heat star Jimmy Butler was limited to 13.

Trailing by 21 entering the fourth quarter, Miami used an 11-0 run to cut the deficit to 10. Highsmith's three-pointer got the gap to nine points with 2:34 to play.

But as they had all night, the Nuggets seamlessly pulled away.

Jokic fed Kentavious Caldwell-Pope for a jump shot, Caldwell-Pope came up with a steal and Aaron Gordon made two free throws as the Nuggets rebuilt the lead.

Jokic added a pair of free throws and a turnaround jump shot and the ecstatic crowd of 19,528 at Ball Arena in Denver could start the celebrations.

"Everybody contributed," Jokic said. "It's a great win for us."

Jokic was content to play facilitator in the first quarter, handing out six assists as the Nuggets clicked quickly despite the 10-day gap since they finished off their sweep of the Los Angeles Lakers in the Western Conference finals.
