OAKLAND -- Don Nelson downplayed a victory over the defending NBA champions minus their superstar, even suggesting an asterisk go alongside this 'W' because Tim Duncan didn't play.
Baron Davis had 18 points, six rebounds and six assists and Golden State took advantage of Duncan sitting out another game with a sprained ankle, beating the sloppy Spurs 96-84 on Tuesday night.
Stephen Jackson had 20 points, five assists and five boards and Matt Barnes had 16 points and eight rebounds as the Warriors used a big second quarter to snap the Spurs' five-game winning streak despite shooting 39 percent.
"We normally don't win these types of games," Nelson said. "Most teams that shoot in the 30 percents don't win. I wouldn't call anything impressive in this game when you beat this team without Tim Duncan. Certainly we're going to take the win."

San Antonio hadn't lost since its last trip to Northern California -- a 112-99 defeat at Sacramento on Nov. 26.
Duncan walked gingerly to the court before the game and was in uniform, but he missed his third consecutive game with a sprained right ankle sustained in a Dec. 2 win over Portland. And the Spurs are far from the same team without him: They committed a season-high 21 turnovers and Golden State scored 24 points off those mistakes.
Matt Bonner led the Spurs with career highs of 25 points and 17 rebounds on a night leading scorer Manu Ginobili was held to 13 points on 4-for-14 shooting after recording back-to-back 37-point performances Dec. 5 against Dallas and Dec. 7 versus Utah.
"I was happy," Jackson said of his defense against Ginobili. "He's been killing everybody -- scoring 37 against everybody."
Andris Biedrins finished with 14 points and seven rebounds and Kelenna Azubuike had 16 points and nine boards for the Warriors, who play at Portland on Wednesday night before returning home to face the Lakers again Friday.
The Warriors are in the middle of one of their best stretches ever. They are 12-3 over their last 15 games, the franchise's best such stretch since also going 12-3 from Dec. 6, 1975, to Jan. 3, 1976.
Ginobili had three points and five turnovers in an unproductive first half, and Tony Parker had a sub-par game with 11 points, six assists and six turnovers. San Antonio (17-4) was trying to extend its franchise-best start.
"Manu had a difficult night -- 82 games, people are people," Spurs coach Gregg Popovich said. "They are not machines."
The Spurs cut the Warriors' lead to 81-70 on Bonner's basket with 9:21 to play, then he hit a 3 with 6:39 left that made it 83-74. But Davis scored on a driving layin moments later.
Davis started the game guarding Bruce Bowen after drawing Dwyane Wade of the Miami Heat on Friday night followed by Lakers star Kobe Bryant on Sunday in Los Angeles.
Golden State guard Monta Ellis strained his left thigh and could be questionable for today's game with the Trail Blazers.
