LeBron James paid tribute to the improvement and maturity shown by Devin Booker after he was beaten in a first-round playoff series for the first time in his NBA career.

The Los Angeles Lakers saw their hopes of repeating as NBA champions ended as they lost 113-100 in Game 6 to the Phoenix Suns, who progress with a 4-2 triumph.

Anthony Davis had to leave the court after only five minutes of his return from a groin injury as Booker produced a stunning performance to finish with 47 points for the Suns.

By the end of the first quarter, Booker had 22 points and had converted all six of his three-pointers, eventually finishing 8-of-10 from behind the arc.

His 47 points, recorded in 46 minutes, were the most to eliminate a defending champion team on their home court in NBA postseason history. 

The surging Suns also won Game 5 by 30 points and led this one by 29 in the first half before James - who had 29 points, nine rebounds and seven assists - helped to make the score more respectable.

But his amazing 14-0 steak in the first round of the playoffs was brought to an emphatic halt and all the plaudits went to Booker.

"I love everything about D-Book," said James. "I've had numerous conversations with him in the past. He continues to make the jump.

"When you want to be great in this league, and as Kobe told him, if you want to be legendary in this game you've got to continue to improve, not only your game but you as a man.

"You have to improve everything, both on and off the floor. And all the conversations we have had over the years, I can tell he's soaked them up and is using them to his advantage.

"Everyone sees what he's able to do on the floor right now, but I think his maturity, him as a young man, is what I'm most impressed about. So I love everything about Book."

Getting himself and the rest of the Lakers team back to full fitness was a bigger concern to James than the end of his playoff streak.

Reflecting on the Lakers' exit, he added: "The season started so fast after leaving the bubble, obviously. 

"I was talking to [Wes Matthews] in the locker room just a few minutes ago, and I said the one thing that bothers me more than anything - we never really got an opportunity to see our full team at full strength, either because of injury or COVID.

"We could never fully get into a rhythm and never really kinda see the full potential of what we're capable of. Listen, as I tell you all throughout the season, every season is different, every challenge is different.

"But they [the Suns] were excellent throughout the series, all of them. Much respect.

"To be able to put myself where I can even have accomplishments – to either be broken or to be able to continue it – it's all though the grace of the man above and me just putting a lot of hard work in, having great team-mates, having great coaching staff, things of that nature.

"So records – if that's a record – they’re always meant to be broken.

"So in that fashion it doesn’t matter to me in so far as not making it out of the first round, what matters to me is getting this team back healthy.

"Me not being able to be at my full strength throughout this series, that’s my main focus. But time to readjust and think about what the off-season has in store."

Past discussions between Booker and late Lakers great Kobe Bryant - also referenced by James - were firmly on the mind of the Suns' star guard after his impressive display.

"Honestly, I was thinking about Kobe and the conversations we had," Booker said.

"About what we went through, and the postseason, and being legendary and taking the steps to get there.

"Seeing that 8 and 24 up there, with the lighting Staples has, it's like it was shining down on you. I know he was here and I know he was proud."
