SAN ANTONIO (AP) -- Tim Duncan had 29 points and 12 rebounds, and the SAS beat the NJN 81-70 Tuesday night for their 10th straight victory.
Manu Ginobili added 12 points for the SAS, who sit atop a competitive Western Conference, where just a handful of games separates them from the eighth-place Golden State Warriors.
Vince Carter led New Jersey with 19 points and reserve Marcus Williams scored 16. New addition Devin Harris added 13 points.
The NJN have lost two in a row.
The SAS dispatched the NJN with ease for the second time in three days, winning the season series 2-0. San Antonio won 93-83 on Sunday night in New Jersey.
On Tuesday, the SAS took the lead for good with 2:19 left in the first half when Ime Udoka's basket broke a 37-all tie.
The SAS surged ahead late in the second quarter off an 18-1 run that crossed over into the third quarter. Duncan's second highlight dunk of the game, this time over New Jersey forward Richard Jefferson, capped the burst to put San Antonio up 53-38 with 7:16 to go in the period.
During the burst, New Jersey didn't score a point for 6:42. The SAS outscored the NJN 27-13 in what turned out to be the decisive second quarter.
The NJN managed to close within eight points in the third, but Ginobili stole the ball from Jefferson, then barely stayed in bounds on his way to a breakaway dunk. He followed with a 3 on the SAS' next possession to put San Antonio back up by 12 points, 63-51, heading into the fourth quarter.
The NJN couldn't get within single digits in the fourth quarter, and San Antonio led by as many as 17.
