SAN ANTONIO (AP) - Luka Doncic had 26 points, 14 assists and 10 rebounds and Kristaps Porzingis added 28 points and 12 rebounds as the Dallas Mavericks powered past the San Antonio Spurs 109-103 on Wednesday night.
Doncic's triple-double was his 13th this season for Dallas, which overcame a disastrous start to the fourth quarter and snapped a four-game skid in San Antonio.
The Mavericks scored only one point in the first six minutes of the final quarter, threatening their dubious league record of two points scored in a quarter in 1997.
DeMar DeRozan had 27 points, nine assists and eight rebounds to lead the Spurs.
Trey Lyle's 3-pointer with 6:16 put the Spurs up 90-89, their first lead since the opening minute of the first quarter.
Losing the lead roused Dallas, who outscored San Antonio 18-7 over the next four minutes to regain control.
The Spurs lost for the seventh time in nine games after going 2-6 on their annual Rodeo Road Trip.
San Antonio forward LaMarcus Aldridge sat out with a sore right shoulder, missing his bobblehead giveaway night. Marco Belinelli added 14 points and Lonnie Walker IV had 12 points while starting in place of Aldridge.
The Mavericks, Porzingis and Doncic particularly, quickly took advantage of the Spurs' smaller lineup.
Porzingis and Doncic combined to score the Mavs' first nine points.
Porzingis scored 16 points in the first quarter on 3-for-4 shooting, including a 27-footer that stunned the crowd. Dallas led 36-20 at the end of the period.
The Spurs shot 29% in the first quarter and finished three points shy of their season low for scoring in the opening period.
