SAN ANTONIO — Tim Duncan had 28 points and 19 rebounds and the San Antonio Spurs escaped with a 92-91 victory over Dallas on Thursday night, sweeping their season series with the Mavericks for the first time in 15 years.
Gary Neal added 16 points and Kawhi Leonard had 12 for San Antonio, which has the Western Conference’s top record at 50-16.
Dirk Nowitzki had 21 points and 11 rebounds for Dallas, which had a four-game winning streak snapped. Darren Collison added 12 points and O.J. Mayo, Mike James, Brandan Wright and Vince Carter had 10 points apiece.
San Antonio last swept Dallas during the regular season in 1998, Duncan’s rookie season.
The Mavericks pulled within 92-91 on a 7-0 run capped by Nowitzki’s fall-away jumper with 28.2 seconds left.
After Manu Ginobili missed a jumper, Carter missed a long, fall-away 3 at the buzzer that would have won the game.
Dallas opened the fourth quarter on a 12-4 run to take its first lead at 78-77 on Nowitzki’s 3, but Neal hit a 3 on the ensuing possession to give San Antonio a lead it would not relinquish again.
The Spurs had five turnovers in the first quarter, enabling the Mavericks to remain within striking distance. Dallas shot 40 percent from the field (8 for 20) in the first quarter, but San Antonio managed only 36 percent (9 for 25).
The Mavericks had an 8-0 run, capped by a pair of free throws by Nowitzki that tied the game at 32.
After Dallas tied the game at 41, the Spurs went on a 13-0 run bridging the second and third quarters. Ginobili had a jumper and an assist on Danny Green’s 3 and Tiago Splitter’s three-point play.
Dallas responded with a 14-4 run, going 6 for 9 to open the third and pull within 58-55.
CLIPPERS: Waived forward Trey Thompkins, who didn’t play in a game this season because of a bone bruise in his left knee.
He averaged 2.4 points and 1.0 rebounds in 24 games as a rookie after being drafted 37th overall out of Georgia by the Clippers in 2011.
The team announced the move Thursday.
