Tim Duncan posted 17 points and 11 rebounds for the division-leading Spurs, who have won three in a row and finished December with a 13-2 record. Manu Ginobili added 15 points and eight rebounds, while Tony Parker had 14 points, six boards and five assists.
The efforts helped make up for the absence of star forward Dirk Nowitzki, who is dealing with a right knee sprain and missed a second consecutive game. Dallas, which has the second-best record in the West behind the Spurs, lost both those games.
San Antonio held a 29-27 edge after the first quarter and built a substantial lead in the second.
Shortly into the frame, the Spurs used three-point shooting to fuel a 14-0 run. Ginobili and Neal both drained two shots from beyond the arc during the rally, which gave San Antonio a 45-29 advantage with under nine minutes left.
The Mavericks, however, used a 10-0 run later in the quarter to stay close and were within 53-46 at the break.
Dallas drew within a point several times in the third quarter, including when Tyson Chandler’s layup made it a 63-62 contest with 3:24 on the clock. But George Hill and Parker followed with a bucket each for the Spurs, who carried a 71-64 advantage to the fourth.
San Antonio then led by at least two possessions throughout the fourth. Dallas made a final run with about three minutes left, when Butler scored six consecutive points to bring the Mavericks within 88-82. However, the Spurs made 9-of-10 free throws in the final two minutes to secure the win.
Kidd recorded the 106th triple-double of his career…Hill scored 12 off the Spurs bench…Chandler finished with 11 boards and eight points for the Mavs…San Antonio held a 50-35 rebounding edge.
