Rui Hachimura, LeBron James and the Los Angeles Lakers made an early statement in the wide-open Western Conference playoffs.

Hachimura scored a playoff career-best 29 points, including 21 in the second half, and James added 21 points and 11 rebounds as the seventh-seeded Lakers beat the No. 2 seed Memphis Grizzlies 128-112 on Sunday in the opening game of their series.

Memphis had the NBA’s best home record at 35-6 but no longer has home-court advantage against LA. Game 2 is Wednesday at FedExForum, and the Grizzlies have major concerns about star Ja Morant, who aggravated a right hand injury.

“We didn’t execute the priorities of the game plan,” Memphis coach Taylor Jenkins said. “Get back. Execute half-court defense and get rebounds.”

Austin Reaves added 23 points, including nine straight in the closing minutes as the Lakers pulled away. Anthony Davis had 22 points and 12 rebounds, and D’Angelo Russell, who scored only two points in the Lakers’ play-in win over the Minnesota Timberwolves, finished with 19 points.

Hachimura missed only one of his nine shots in the second half, including making all five of his 3-point attempts.

“The second half, we were in a good rhythm,” Hachimura said. “We were sharing the ball and all the shots just came to me.”

Reaves added: “Rui was huge (Sunday). His skillset is crazy. For us to get him with all the talent we have, it just brings another aspect to our team.”

Jaren Jackson Jr. led Memphis with 31 points, while Desmond Bane scored 22. Morant had 18 points before leaving in the fourth quarter with the hand injury. The Grizzlies’ leading scorer’s availability for Game 2 is uncertain.

“I’m in a good bit of pain,” Morant said. “My main focus was to be out there for my guys. Another incident where, you know, that’s pretty much in jeopardy.”
