DALLAS — Luka Doncic got the help he and the Dallas Mavericks needed — from Jalen Brunson on offense and himself, Reggie Bullock and others on defense.

The Dallas superstar had 26 points and 13 rebounds, and the Mavericks turned up the defensive pressure to get back in their Western Conference semifinal series with Phoenix, beating the Suns 103-94 on Friday night.

The Mavericks spoiled Chris Paul’s 37th birthday, forcing the 17-year pro into his most turnovers in any half of a playoff game with seven before the break.

Dallas cut the Suns’ series lead to 2-1 and ended an 11-game losing streak against Phoenix, regular season included. Game 4 is Sunday in Dallas.

“Energy, man,” Doncic said of the best Dallas defensive showing of the series. “The crowd gets you going. The energy and the execution were better. That’s what we’ve got to do every game.”

Paul didn’t have any more turnovers after halftime, but the Suns finally struggled with their shooting when they weren’t turning it over. Phoenix shot 45 percent, ending a run of at least 50% shooting in the playoffs at eight games.

“It felt like all seven of ’em were back to back to back,” said Paul, whose career high for a game in the playoffs is eight turnovers. “If I don’t turn the ball over like that I feel like it’s a different game.”

Jae Crowder scored 19 for Phoenix, but the Mavericks limited the impact of Devin Booker in much the same way they did Paul. Booker scored 18 but was just 2 of 7 inside the 3-point line, and Paul had 12 on just nine shots (five made) in the Suns’ lowest-scoring game of the season.

Doncic just missed a triple-double with nine assists, while Brunson led Dallas with 28 points after struggling in the two losses in Phoenix when Doncic averaged 40 points but didn’t get enough help.

“I found a way to bounce back tonight,” Brunson said. “I just can’t be satisfied with this. Sunday’s going to be another brutal game. I have to bring the same energy, the same intensity, the same everything.”

A scrambling Dallas defense was the biggest difference, starting from the opening tip with Bullock shadowing Paul everywhere. The Mavericks stepped into passing lanes, including when Spencer Dinwiddie tiptoed along the sideline after a steal for a layup in transition.

Paul had six turnovers in the first 16 minutes, including one when he simply lost the ball out bounds trying to work his way to the basket. The only Dallas turnover before halftime was an offensive foul on Doncic, who disliked the call enough to mimic what he thought were flopping movements by Paul.

The Suns targeted Doncic’s defense when shooting 84% to pull away in the fourth quarter of a 20-point win in Game 2. The 23-year-old Slovenian dove to the court early in this one, winning a battle with Deandre Ayton for a loose ball.

“When you see your best player doing that, it kind of sets a mood,” Dorian Finney-Smith said.

Doncic had to leave with his fifth foul early in the fourth quarter, and the Suns cut an 18-point deficit earlier in the second half to nine just after he came back.

Brunson answered with free throws to get the lead back to double digits, and the Mavericks got enough stops to stay comfortably in front.

The lead was eight when Doncic kept Crowder from getting a steal near midcourt with a minute remaining, leading to a corner 3 with from Bullock, who scored 15. He and Finney-Smith, who scored 14, had four 3s apiece.

“It wasn’t like us,” Booker said. “You can credit them. They came out played hard, played desperate. That’s that. We’ve got a series.”
