Caron Butler added 23 points on 10-of-14 shooting. Baron Davis led New Orleans with 23 points.
Rockets 90, Grizzlies 87
In Houston, Tracy McGrady left in the third quarter with a hip injury, as Houston hung on beat the winless Memphis.

Kings 108, Raptors 92
In Sacramento, California, Chris Webber had a triple-double to help Sacramento win its first game of the season and hand Toronto its first loss.

Jalen Rose and Rafer Alston scored 15 points each for the Raptors, who opened a six-game West Coast road trip after winning their first three games at home.
The NBA suspended Milwaukee Bucks forward Marcus Fizer on Tuesday for one game following his guilty plea on a gun charge.
Fizer, who signed with the Bucks last Thursday, is currently on the injured list with a knee injury and out four to six weeks. He will serve the suspension when he is healthy enough to play.
The former Chicago Bulls player pleaded guilty in August to carrying a loaded handgun in his car. Fizer was sentenced to a year's probation and fined US$2,500.
