DALLAS — Luka Doncic has his first victory in an elimination game.

Now the young Dallas superstar gets another one — and another Game 7 to boot.

Doncic scored 33 points and the Mavericks beat the Phoenix Suns 113-86 on Thursday night to force a deciding game in the Western Conference semifinals.

The home team has won all six games, none with a margin closer than seven points. A trip to the West finals will be at stake Sunday in Phoenix.

The Mavericks won when facing elimination for the first time in three tries with the 23-year-old Doncic, their three-time All-Star point guard.

The two losses came against the Clippers the past two seasons, including Game 7 in Los Angeles last year after the visitors won the first six games, a first in the playoffs. Dallas is playing beyond the first round for the first time since winning the title 11 years ago, when first-year coach Jason Kidd was the point guard.

“I don’t know if he was playing as if he was trying to do something different,” Kidd said. “I think he enjoys the moment.”

The Suns, seeking a second consecutive trip to the conference finals, are going the distance in a series for the first time in two postseasons with Chris Paul and Devin Booker. The previous three went six, including Phoenix’s loss to Milwaukee last year in the NBA Finals.

Booker scored 19 points but was shut out from 3-point range (0 of 4) while going 6 of 17. Deandre Ayton had 21 points and 11 rebounds, and Paul added 13 points.

The top-seeded Suns were held to a season low in scoring, regular season or playoffs, for the second time in the series. They shot a playoff-low 40% with 22 turnovers, the most all season.

“I don’t have enough time to talk about everything that’s eating at me,” coach Monty Williams said. “I didn’t think we understood the desperation they were going to play with. Couple that with the turnovers that we had tonight, it’s a recipe for what we just got.”
