Marcus Thornton added 17 points of his own off the bench.
Sacramento shot just 35.2 percent from the field and was just 3 of 16 from the three-point line as they struggled throughout the night to find any rhythm.
Tim Duncan turned back the clock and looked like his vintage self, leading all scorers with 23 points. He also had 12 rebounds, three steals and four blocked shots in 31 minutes for the Spurs. San Antonio won the battle of the boards and grabbed 48 boards against Sacramento's 43. The Spurs also dished out 27 assists as the scoring came much easier for the visitors.
With the loss, Sacramento moves to 2-4 on the season while the Spurs are now 5-1. The Kings will travel to Los Angeles to face the Lakers on Sunday in an effort to rebound from the loss.
