LeBron James had his best game of the NBA Finals, averaging 23.0 points, 7.0 rebounds, 2.7 assists, 1.5 steals and 1.4 blocks.
He scored a career-high 24 points on 11-of-17 shooting.
The Cavs also defeated the Golden State Warriors 106-97 on Monday night, their sixth straight victory.
Cleveland’s win was the most points the Cavs have scored in the series.
James scored 25 points on 8-of, 9-of shooting and made three 3-pointers.
Cleveland shot just 33 percent, but still got a big cushion from the Warriors on the boards, including 11 offensive rebounds.
James also had six assists.
“The first game, I thought we played a very good game, and it was a good game,” Cavs coach Tyronn Lue said.
“We were playing good defense.
But it’s always nice to come out and win a game, especially the first game of a series.”
Kyrie Irving scored 21 points for the Cavs, who are trying to make it four straight wins.
Cleveland has won four of the past five meetings.
“They just went down a few holes in the game.
They were down 20 in the second half, but they didn’t take it.
They made some really good plays,” Lue told the team’s official website.
“Their bigs were able to get to the basket, and we made some great plays.”
Golden State is still trying to figure out how to stop Kyrie.
The Warriors are 7-2 when he scores at least 25 points.
James and Irving have been the only players to score more than 20 points in each game this series.
“I think we were really good tonight, and I think we can take that confidence out of us,” Irving said.
The Cavaliers are 5-0 in the Finals when James scores at or near 50 points.
The last two meetings were in Cleveland.
James has scored at least 30 points in all four games.
“He’s the MVP of this franchise,” Cleveland coach Ty Lue laughed.
“It’s hard to say no to him.
He’s going to do it every night.
He did it again today.
He was just a monster.
He played unbelievable.
I don’t think he’s a guy who’s going away, but we’re going to go out there and have fun.”
Golden States center Zaza Pachulia added 19 points and 11 rebounds.
The game was the first time the Warriors were without Draymond Green and Jarrett Jack, who were each injured.
They have averaged 17.4 points and 15.3 rebounds in the last three meetings.
Golden State has won five straight in Cleveland and 12 of 15 overall.
