Chris Paul compared the Phoenix Suns to a wrestling tag team after they beat the Denver Nuggets 122-105 in their NBA playoffs semi-final opener.

In front of what Paul described as "crazy" home support, the Suns bossed the second half 65-47 to take first blood in the Western Conference last-four series.

Paul (21 points and 11 assists) and Deandre Ayton (20 points and 10 rebounds) fuelled the second-seeded Suns, who saw all of their starters finish with double-digit points – Devin Booker (21), Mikal Bridges (23) and Jae Crowder (14) making priceless contributions.

With the likes of Cameron Payne and Torrey Craig coming off the bench – the latter having nine points and eight rebounds in under 18 minutes on court – there are good grounds for optimism in the Suns ranks.

Paul said the key to the Suns second-half surge, after slipping 70-60 behind at one point, was "just playing with pace", and a vibrant home atmosphere, with Olympic swimming great Michael Phelps among the crowd.

"They got a nice little lead on us there in the third quarter," he said. "This crowd is crazy. It's crazy. To have the fans in there, the energy, there's nothing like it.

"I told the guys this is why we fought so hard during the regular season to get home-court advantage. I think we truly have that with our fanbase here."

For Denver, MVP favourite Nikola Jokic was limited to 22 points on 10-for-23 shooting, nine rebounds and three assists on the road.

Paul said the Suns have real character as a unit.

"It's fun to be on the team," he said. "It's almost like wrestling and you're tagging in.

"You go out of the game and there's no drop-off, there's just another unit coming in and keeping pressure on you.

"I think that's the benefit of having the team like we have."

The second game in the series takes place on Wednesday, again at the Phoenix Suns Arena.

While Paul praised others, Booker hailed Paul's contribution.

"We felt that energy. We felt that passion behind it," Booker said.

"He just made plays. Not only his scoring ability but getting everybody else involved. That's been the story of the season for us, following him in that regard."
