LOS ANGELES: Jayson Tatum scored 33 points as the Boston Celtics ended the Cleveland Cavaliers’ 15-game unbeaten start to the season with a hard-fought 120-117 victory in the NBA Cup on Tuesday.

The Celtics unleashed a barrage of 22 three-pointers to overwhelm Cleveland, who clawed their way back to within two points of the lead late in the game after trailing by 21 early in the second half.

But despite the Cleveland fightback, reigning NBA champions Boston held their nerve and kept the scoreboard ticking over to close out a deserved win.

Tatum’s 33 points included six three-pointers while the Boston star added 12 rebounds and seven assists in an all-round Celtics effort that saw six players finish in double figures.

Tatum said Boston’s championship pedigree had helped the Celtics over the line as Cleveland threatened late in the game.

“We’ve played a lot of basketball, we’ve played in the biggest games,” Tatum said. “NBA is a bunch of talented teams — guys are gonna make plays, they’re gonna make shots.

“I say it all the time — how you respond shows your growth and how special your team is.”

Tatum admitted that ending Cleveland’s unbeaten record, which has left them sitting on top of the Eastern Conference, had motivated the Celtics.

“They came in 15-0 feeling like they were the best team; we felt like we were the best team — it’s all competition. We were ready to play today,” Tatum said.

Cavaliers coach Kenny Atkinson said his team had been caught off-guard by Boston’s superior intensity.

“The they had playoff force and physicality — we had regular season force and physicality,” Atkinson said. “That’s why we were down by whatever we were down. Second half we turned it up, but it was kind of too late. We’re just going to have to put it in the bank and make adjustments.”

Boston were quickly into their stride, rattling in five early three-pointers to sprint into an 18-8 in the opening minutes of the first quarter.

Cleveland rallied to reduce the deficit to 26-20 at the end of the first quarter, but the Celtics kept up the pressure in the second.

Tatum drained a superb three-pointer in the final seconds of the first half to give Boston a commanding 65-48 lead at the break.

The Celtics stretched into a 21-point lead early in the second half, but the Cavaliers clicked into gear and came roaring back to close the gap to two points at 88-86.

Tatum though had the last word, nailing an imperious three-pointer to give Boston a five-point lead heading into the final quarter.

A nip-and-tuck final period saw Cleveland repeatedly close to two points but Boston pulled clear in the final minutes to seal victory.

Donovan Mitchell led Cleveland’s scoring with 35 points while Evan Mobley added 22 with 11 rebounds and six assists.

In other early games on Tuesday, the Brooklyn Nets defeated the Charlotte Hornets 116-115 thanks to a 34-point display from Cameron Johnson.

MALLORCA: Rafael Nadal said he has left both a sporting and personal legacy after retiring from professional tennis on Tuesday at the Davis Cup.

The 38-year-old was beaten in the opening singles rubber of the quarterfinals as Netherlands defeated Spain 2-1 to reach the final four.

Nadal, a 22-time Grand Slam winner, enjoyed a glittering and historic career over the past 23 years.

“I leave with the peace of mind that I have left a legacy, which I really feel is not just a sporting one but a personal one,” Nadal told fans in Malaga in a speech during a ceremony to honor his retirement.

“I understand that the love I have received, if it was just for what happened on the court, would not be the same.”

Nadal paid credit to many who have helped him along the way, including his uncle Toni Nadal, who coached him as a child and for a large part of his career.

“The titles, the numbers are there, so people probably know that, but the way that I would like to be remembered more is like a good person, from a small village in Mallorca,” continued Nadal.

“I had the luck that I had my uncle that was a tennis coach in my village when I was a very, very small kid, and a great family that supports me in every moment...

“I just want to be remembered as a good person, a kid that followed their dreams and achieved (even) more than what I had dreamed.”

Nadal was celebrated with a video montage on the many screens around the Martin Carpena arena in Malaga where over 10,000 fans saw his career come to a close.

Former rival Roger Federer, Novak Djokovic, Andy Murray, Serena Williams and other tennis greats left messages in the video, alongside former Spanish football stars including Raul and Andres Iniesta, who retired from playing in October.

“I leave the world of professional tennis having encountered many good friends along the way,” said Nadal in his emotional speech.

The Spaniard said he hoped to be a “good ambassador” for tennis in the years to come and was not afraid to begin his retirement.

“I am calm because I have received an education to take on what is coming next,” he explained.

“I have a great family around me who help me with everything that I need every day.”
