CLEVELAND — LeBron James figured he had experienced everything in 12 postseasons.

Turns out, there was something new.

Victor Oladipo scored 32 points and Indiana outplayed Cleveland from the start while pulling off a stunning 98-80 victory Sunday in the series opener, handing James and the Cavaliers' their first loss in the opening round in eight years.

It also was the first playoff-opening loss for James, who came in 12-0 in Game 1s and didn't realize he had been perfect starting the postseason.

"Is it?" James said. "I've never lost a game in the first round before in my career?"

But while he knows the narrative before Wednesday's Game 2 will be on the struggles of Cleveland's playoff newcomers, James isn't worried.

"I'm down 0-1 in the first round," he said. "I was down 3-1 in the Finals. So, I'm the last guy to ask about how you're going to feel the next couple days."

Indiana opened a 21-point lead in the first quarter and pushing it to 23 in the third. The Cavs got within seven in the fourth, but Oladipo hit a big 3-pointer and Bojan Bogdanovic hit another to to make it 88-71.

When the final horn sounded, the Pacers calmly walked off, business as usual.

"We believe that we can win," Oladipo said. "We came into this game with a mentality that we wanted to attack on both ends of the floor and play the way we've been playing all year, and we did a great job of that. It's only one game, it's only Game 1."

The Pacers completely outplayed the three-time defending conference champions, whose turbulent regular season has carried over into the playoffs.

James scored 24 with 12 assists and 10 rebounds for his 20th career triple-double. But James got little help as Cleveland's four other starters — Kevin Love, Jeff Green, Rodney Hood and George Hill — combined for 25 points.

"They were more aggressive," James said. "They just played inspired basketball and they just took advantage of everything we wanted to try and do. They were more physical than us at the point of attack, and they were most precise with what they wanted to do and we couldn't score the ball."

Thunder 116, Jazz 108: Paul George scored 36 points to help the Oklahoma City Thunder defeat the Utah Jazz in Game 1 of their Western Conference playoff series.

George set an Oklahoma City playoff record with eight 3-pointers, blowing past the previous record of five. He made eight of 11 shots from long range, and 13 of 20 shots overall in his first playoff game with the Thunder since being acquired in an offseason trade with the Indiana Pacers.

Russell Westbrook had 29 points, 13 rebounds and eight assists and Carmelo Anthony added 15 points for the Thunder, who will host Game 2 on Wednesday.

Jazz rookie Donovan Mitchell had 27 points and 10 rebounds, but he left in the second half with left foot soreness. Rudy Gobert scored 14 points, and Joe Ingles and Jae Crowder each added 13.

76ers 130, Heat 103: Ben Simmons had 17 points, 14 assists and nine rebounds in his playoff debut, and the Philadelphia 76ers romped again without Joel Embiid, beating the Miami Heat on Saturday night for their 17th straight win.

JJ Redick scored 28 points to lead the Sixers. Marco Belinelli had 25 and Ersan Ilyasova 17.

Former Boston Celtic Kelly Olynyk led the Heat with 26 points.

Pelicans 97, Trail Blazers 95: Anthony Davis had 35 points, 14 rebounds and four blocks, and the New Orleans Pelicans beat the Portland Trail Blazers on Saturday night in Game 1 of their playoff series.

Jrue Holiday added 21 points  and had a big blocked shot in the closing seconds as New Orleans held on after Portland erased almost all of a 19-point deficit. Rajon Rondo finished with 17 assists, eight rebounds and six points.

Damian Lillard finished with 18 points, seven rebounds and seven assists for Portland, while CJ McCollum had 19 points.
