The Warriors hadn't beaten the Spurs at home since Valentine's Day 1997, and there's still no love at the AT&T Center.
Tim Duncan showed why he's still the best center in the NBA, dominating the Warriors for 25 points, 13 rebounds, and 4 blocks.
Stephen Curry led the Warriors with 24 points and Jarrett Jack added 14 points and seven assists off the bench.
Andrew Bogut played 30-plus minutes scoring four points and 11 rebounds.
Golden State missed 15-of-24 shots in the second quarter but staged a valiant comeback in the fourth to come within four at the 3:38 mark. However, Duncan took over and scored a reverse layup off a steal to close the game.
Despite the loss, Coach Mark Jackson was satisfied with the 2-1 road trip saying "We looked like our old selves."
The Warriors (39-31) remain a game ahead of the Houston Rockets for the No. 6 seed in the playoffs.
Golden State faces the Washington Wizards on Saturday, March 23 at Oracle Arena.
