TORONTO — This time, LeBron James didn't have to do it all by himself.
James had 26 points, 13 assists and 11 rebounds for his 21st career playoff triple-double, J.R. Smith scored 20 points and the Cleveland Cavaliers beat the Toronto Raptors 113-112 in overtime on Tuesday night to win Game 1 of their second-round playoff series.
Kyle Korver scored 19 points, including the go-ahead 3-pointer in overtime after Cleveland never led in regulation. Tristan Thompson had 14 points and 12 rebounds for the Cavaliers, who have eliminated Toronto in each of the past two postseasons.
"My teammates were unbelievable tonight," James said. "They stepped up when I wasn't at my best."
Jeff Green scored 16 points and Kevin Love had 13 rebounds.
James, who topped 40 points three times in seven games against Indiana in round one, shot 12 for 30 against Toronto, going 1 for 8 from 3-point range, and called it "probably one of my worst games of the season."
Still, James came through when it counted, tying the score with two baskets in the final 92 seconds of regulation to complete Cleveland's comeback from a double-digit deficit.
"It got to a one-possession, two-possession game," James said. "That's what I like the most."
Toronto's Fred VanVleet missed a 3-pointer with 3.4 seconds to go in overtime that could have won it for the Raptors, who couldn't hold on after taking a 10-point lead early in the fourth quarter.
"He got a heck of a shot," Raptors guard DeMar DeRozan said. "I'll live with him shooting that shot 10 times out of 10. We got a good look and it just didn't fall."
Jonas Valanciunas had 21 points and 21 rebounds, Kyle Lowry had 18 points and 10 assists, and DeRozan scored 22 points for the Raptors, who host Game 2 on Thursday night.
The Cavaliers beat the Raptors in six games in the Eastern Conference finals in 2016 before going on to win their first NBA championship. Last year, Cleveland swept Toronto in the second round.
Korver's 3 early in overtime gave the Cavaliers their first lead of the game, 108-105.
Lowry's three-point play made it 113-112 with 57 seconds to go and, after the Cavs were called for a shot-clock violation, Toronto had one more chance to win, but VanVleet couldn't come through.
"We feel good about the win but I think we were also very fortunate," Korver said.
VanVleet was one of four Raptors to miss in the final seconds of regulation. Toronto got four looks at the potential winning basket but missed all four, including a wide-open 3 by VanVleet, giving Cleveland the ball with 0.6 seconds remaining. Green inbounded to James, but his shot bounced off the rim.
The Raptors shot 5 for 24 in the fourth quarter, with Valanciunas missing six of seven attempts. Toronto missed its final 11 shot attempts in regulation.
"I don't know if it was nerves or yips or what," Raptors coach Dwane Casey said. "Just things that shot ourselves in the foot when we had a 10-point lead."
DeRozan scored 11 points in the first, connecting on five of eight attempts, and Lowry had eight points and five assists as Toronto led 33-19. James was 3 of 5 in the first but the rest of the Cavs shot 4 for 18.
James, who averaged more than 41 minutes in Cleveland's first-round series against Indiana, checked out with 3:31 left in the first. With James on the bench, the Cavs scored two points the rest of the quarter.
Green and Smith each scored 11 points in the second and the Cavs found their shooting stroke, connecting on 14 of 22 attempts. James had five assists in the period as Cleveland cut the deficit to 60-57 at halftime.
VanVleet took exception to a shove from James at the end of one play and made an attempt to get at the Cavs star, but was restrained by teammates.
Valanciunas had 13 points and eight rebounds in the third, but Korver scored 10 points and James had eight to keep the Cavs close. Toronto led 87-82 heading to the fourth.
"He was kicking our butt in the third quarter," James said of Valanciunas. "Luckily, I just felt like he wore down a little bit in the fourth."

LEAVING IT LATE
According to ESPN, the Cavs are the second team in the past 20 postseasons to win a game in which they never held a lead in regulation. The only other team to do it was Dallas, which won at Oklahoma City on May 23, 2011.
Cleveland's Kendrick Perkins traded angry words with rapper Drake, Toronto's global ambassador, as the teams walked off at halftime, and again at the end of the game. Former Raptors guard Jose Calderon stood in front of Drake during the halftime exchange as Smith gently moved Perkins toward the locker room.
