PHILADELPHIA -- LeBron James and Kevin Love carried the Cleveland Cavaliers through three quarters.

Kyrie Irving did the rest down the stretch.

Irving scored 20 of his 39 points in the fourth quarter, Love had 25 points and 11 rebounds and the defending champion Cavaliers rallied from an early 14-point deficit to defeat the Philadelphia 76ers 112-108 on Sunday afternoon at the Wells Fargo Center.

"When you have great players, it can come from any of us at any given moment," said Irving, who shot 14-of-27 from the field. "When one of us gets it going, we always continue to go to that person. It can be anybody's night. We're always trusting each other. That fourth quarter was just for me to be aggressive."

James added 26 points, 13 assists and 10 rebounds for his third triple-double of the season and Tristan Thompson contributed 12 points and 12 boards for the Cavaliers (13-2), who own the best record in the Eastern Conference. It's also the best 15-game start in the history of the franchise.

"Whoever has the hot hand, we want to continue to get it to him," James said. "Kyrie understands what needs to be done in order for us to win. He showcased that today."

Cleveland beat the Sixers for the eighth straight time.

Joel Embiid led Philadelphia (4-13) with 22 points and nine rebounds, and Jahlil Okafor added 14 points and nine boards. Ersan Ilyasova and Gerald Henderson scored 13 points each, Sergio Rodriguez had 12, Nik Stauskas contributed 11 and Dario Saric added 10.

"They can go to another level and they did," 76ers coach Brett Brown said. "We all felt it and saw it. I feel that's the lesson we all learned since we've been together."

Philadelphia closed a five-game homestand at 2-3. After winning the first two games against the Phoenix Suns and Miami Heat, the Sixers dropped home games against the Memphis Grizzlies, Chicago Bulls and Cavaliers.

"I think we're getting better," Brown said. "I'm proud of their effort against the NBA champs."

The Sixers led 81-71 late in the third quarter before the Cavaliers responded with six straight points to close the advantage to four at 81-77.

Irving became red hot in the fourth with 13 early points as the Cavaliers surged to a 97-89 lead with 5:45 remaining. Irving's 3-pointer from the baseline as the shot clock expired gave them an eight-point lead.

Irving, who scored 19 points in the final 12 minutes, drove coast to coast and scored again for a 100-91 lead with 4:20 left.

"Kyrie being Kyrie," Cleveland coach Tyronn Lue said. "We know he can score the basketball and we needed him to score the basketball tonight."

"He was making shots all over the place," Embiid added of Irving. "That's why he's a superstar."

Ilyasova knocked down a 3-pointer and was fouled with 1:00 left for the unconventional four-point play, cutting the Cleveland lead to 108-103.

On the ensuing possession, James worked most of the shot clock and hit a layup with 37.1 seconds remaining for a seven-point advantage.

Cleveland's come-from-behind win occurred without much of a contribution from J.R. Smith, who was 0 of 11 from the field and 0 of 7 from beyond the arc.

"Yeah, keep shooting," Lue said. "As a shooter you're not going to make every shot. Defensively, he was great like he's been all year. His shots are going to fall. When they do, we'll be really tough to stop."

Amazingly, the Cavaliers missed their first 14 shots before James finally converted a driving layup with 6:50 left in the first quarter.

The Sixers pulled out early and led 30-24 after the first quarter thanks to eight strong minutes from Embiid that included six points, five rebounds and two blocked shots.

The Cavaliers slowly chipped away, got within 49-40 and then crept closer at 49-43 with 5:00 remaining before halftime. The 3-pointer by James closing the gap to six was a major milestone as it marked his 1,000th career 3-pointer in a Cleveland uniform.

James is the only player in franchise history to knock down 1,000 shots from beyond the arc.

Philadelphia then reeled off seven straight points capped by a short jumper by Okafor. Coming off the bench, Okafor struggled in recent games. This time, he was aggressive from the start and wound up with 10 points and six rebounds in the first half.

As championship teams do, Cleveland rallied and went into the locker room trailing 58-52.

James led all scorers with 18 points in the first half.
