LeBron James scored 15 of his 31 points in the fourth quarter, and the Los Angeles Lakers secured the last semifinal spot in the inaugural NBA In-Season Tournament with a 106-103 victory over the Phoenix Suns on Tuesday night.

Anthony Davis had 27 points and 15 rebounds and Austin Reaves scored 20 for the top-seeded Lakers, who will face New Orleans on Thursday in Las Vegas. Milwaukee plays Indiana in the East semifinal.

“You’ve got some of the most alpha male competitors in the world, and if you give us an opportunity to play for something meaningful or an incentive, then you get what you’re getting,” said James, who also racked up 11 assists, eight rebounds and five steals. “The In-Season Tournament is what it is, and we have an opportunity to play on a big stage, be on national television, represent our families, our communities, where we come from.”

Kevin Durant scored 31 points, but he badly missed a long 3-point attempt at the buzzer for the Suns. Phoenix had won eight of 10 before losing to Los Angeles for the third time already this season. Devin Booker cut the Lakers’ lead to 102-101 on a layup with 29 seconds to play, but Reaves drilled his third 3-pointer with 15 seconds left.

After Durant made another layup moments later, the Suns were left furious when officials granted James’ request for a timeout while the ball appeared to be loose because Booker had knocked it away from Reaves an instant earlier.

“It’s a loose ball, and you can’t call a timeout on a loose ball,” Phoenix coach Frank Vogel said. “The whistle blows. I don’t know why. Everything in the league is reviewable. I don’t know why that can’t be reviewable. … We got the trap, we got the turnover, (and the) damn whistle blows. It’s just frustrating.”
