The Lakers built a huge early lead against Phoenix only to see it shrink to single digits. They still won their third game in a row but considered it a lesson learned.
LeBron James notched his eighth triple-double of the season and Anthony Davis had 26 points and 11 rebounds as the Western Conference leaders opened 2020 with a 117-107 victory.
"We can't allow ourselves to fall into a trap like that," Davis said. "You got to learn how to handle success within games."
James finished with 31 points, 13 rebounds and 12 assists in a game that appeared well in hand by the end of a dominant first quarter. He had double-figure points and assists by half-time.
"We wanted to get off to a good start and protect home as well as we can," James said.
The Suns rallied in the fourth, getting within seven points after trailing by 36 earlier in the game. That forced the Lakers' starters back in, and James steadied them with eight points to close out the win.
"You always got to be engaged until the clock hits zero," James said.
The Lakers shot 70 per cent in a ferocious opening quarter when they made their first 11 shots. Danny Green had their first miss on a three-point attempt, but the Lakers controlled the offensive rebound and JaVale McGee found Green for a dunk.
"I'm asking our guys to dominate everybody they play," Lakers coach Frank Vogel said. "Our guys took that message to heart."
The Lakers missed just eight attempts in the first quarter. James airballed a shot, but they snagged the rebound and Avery Bradley scored to salvage the possession.
The Lakers put together a 25-4 run in which the Suns were limited to only free throws. Among the highlights, Davis dunked over Aron Baynes and let out a roar, and later threw down a reverse dunk on James' pass.
Not to be outshone, James followed with a two-handed jam that ignited the crowd. Los Angeles led 43-17 at the end of the quarter.
Devin Booker scored 32 points and Kelly Oubre J. added 26 for the Suns. Phoenix had won two in a row after losing eight straight.
"We turned it up a notch in the second half and came out swinging," Booker said. "We did it with defense and a will to play and a competitive spirit. We know we can do it. We'll figure it out. Anytime you go 2-2 on a road trip, it's a good road trip."
Phoenix's DeAndre Ayton scored 16 points in his second game back from a sprained right ankle. He pulled down a game-high 14 rebounds in 31 minutes.
"I'm trying to get my rhythm back," he said. "We got down early but we woke up in the second half. I take this personal and I'm taking it home with me. We need to start games the way we ended the game and put fear into our opponents and pressure the rim."
