Ginobili keyed a late spurt in the first half that turned a five-point lead into a 12-point halftime edge. He assisted on a 3-pointer by Kawhi Leonard and scored the final two baskets of the half, the last a pull-up jumper with less than a second left for a 57-45 lead.
The Spurs ran out to a 20-6 lead on midrange jumpers from Parker, who scored 10 in the first quarter, and a couple of 3-pointers from Danny Green, who had a career-high seven from long range against Dallas a week ago. Green finished with eight points and was 2 of 3 from beyond the arc.
The Mavericks closed the gap late in the first behind Elton Brand, who scored six in the first quarter after going scoreless for the second time this season two nights earlier against Denver. Brand had 14 points and 10 rebounds.
O.J. Mayo, Dallas' leading scorer, was held under 10 points for the third time in four games. He came in averaging 9 points on 33-percent shooting the previous four games and finished with eight on 4 of 14 shooting. Green blocked two of his 3-point attempts in the second half, including one after Mayo tried a pump fake that instead just gave Green enough time to get there before Mayo shot it.
