The Spurs gave away a 14-point lead in the third quarter. They opened the fourth on a 17-5 run over the first six minutes and won the quarter 30-17, as Spurs fans took over American Airlines Center late, the AP said.
San Antonio won the possession game. It grabbed 15 offensive rebounds and outscored Dallas 25-10 on second-chance points, and the Mavericks committed 18 turnovers to the Spurs' 12. Dallas scored 46 points in the paint in the first half, a franchise high in the play-by-play era according to the Elias Sports Bureau, but only 16 more after halftime.
Dallas starters combined for 50 points, with P.J. Washington and Daniel Gafford scoring 12 each. Gafford added nine rebounds and three steals.
Both teams are 1-2. San Antonio hosts Sacramento on Tuesday, and Dallas visits winless Miami on Monday.
