Dirk Nowitzki scored only 13 points on three-for-11 shooting, made seven turnovers and got a technical foul while sitting on the bench for the Mavericks (52-10). Dallas hadn't lost since Jan. 25 at Chicago.

Jason Terry scored 16 points, but Dallas never was competitive in only its third loss in three months.

Mickael Pietrus scored 20 points for Golden State. Eight players scored at least eight points for Golden State, including 16 apiece from Stephen Jackson, Al Harrington, Andris Biedrins and Jason Richardson.

The Mavericks beat the Lakers by 36 points Sunday night to improve to 38-2 since Dec. 11 but played awful defense against the Warriors while falling behind by 17 in the first half and 29 in the third quarter.

Don Nelson, the Mavericks' longtime coach in his first season back with Golden State, has won his first two matchups with former protege Avery Johnson.

Golden State scored the first eight points, and it never got much better for Dallas. Nowitzki went scoreless in the second quarter, and Dallas gave up runs of 11-0 and 10-4 while falling behind, 62-45, late in the first half.

Nowitzki became visibly frustrated in the third quarter, flattening Baron Davis for an offensive foul, then knocking a loose ball out of a cameraman's hands in his fury.

Johnson removed him from the game and Harrington made a free throw to put Golden State ahead by 23.

Two possessions later, Nowitzki was whistled for a technical foul for complaining from his seat on the bench.
