The Sixers scored just 21 points in the fourth quarter, and couldn't get their shots to fall as a result of the stifling San Antonio defense.
Tim Duncan returned from a night off to rest and led the Spurs (33-11) with a game-high 24 points on 10-of-17 shooting from the field, adding 17 rebounds, five assists, two steals and one block. Kawhi Leonard had five key points late in the fourth quarter to help put the Sixers away for good, finishing with 16 points, seven rebounds and two steals.
Philadelphia (17-24) had a dismal first half before turning things around and scored just 35 points. In the first two quarters combined, they were just 15-of-43 from the field, including 1-for-6 from the three-point line. They used a strong third quarter to get the game back within reach, however, shooting 61.9 percent from the field and turning the ball over just twice while scoring 18 points in the paint.
San Antonio came into the evening with the NBA's third-best record, and managed to turn things around on the road having lost seven of their previous nine road games.
