Rookie Will Bynum and Andris Biedrins added 14 points apiece for the Warriors (33-47), who have won three straight games for the first time since late December.

The ninth overall pick in June's draft, Diogu scored in double figures in for the fifth straight game by making 4-of-7 shots and 7-of-8 free throws in 32 effective minutes.

"I feel I'm finally coming around this last stretch, getting more minutes and being a lot more productive," Diogu said. "Just showing people what I can do. That's basically what I'm setting out to do."

"Ike (Diogu) can score," Warriors coach Mike Montgomery said. "When they go small we have the luxury of moving him over and playing him at the five. He's making progress."

Diogu's driving layup less than two minutes into the third quarter gave the Warriors the lead for good at 42-41. They held a 63-57 advantage entering the fourth quarter.

Golden State held a 50-33 rebounding advantage. The Blazers matched a franchise low with just three offensive boards.

Rookie Martell Webster and Juan Dixon scored 17 points each for Portland (21-59), which has lost six straight and 17 of its last 18 games.

"We were a step slow tonight," Trail Blazers coach Nate McMillan said. "We didn't have the movement that we showed in the last two games (in Los Angeles). We just seemed to be standing around on offense, letting them get most of the loose balls."
