AUBURN HILLS, Mich. — If not for rookie Ike Diogu, Golden State's five-game road trip might have been almost a total loss.

In and out of the rotation since his return from a hand injury a month ago, Diogu scored a career-high 27 points and tied a career high with seven rebounds in 32 minutes Friday, but the Warriors still lost their fourth straight game 97-85 to the Detroit Pistons at The Palace.

Golden State (14-13) has lost seven of its past nine to fall to fourth place in the Pacific Division after toying with first much of the first six weeks.

The Warriors' only win during their five-game, eight-day East Coast swing came Dec. 16 against lowly Toronto. They allowed 106.6 points per game during the trip, and Detroit shot 48 percent.

"It's hard to put a thumb on exactly what went wrong," Warriors coach Mike Montgomery said. "But I don't think our emphasis, our priority is solid enough on defense. I don't think there's a sense of urgency there that we've got to get the job done across the board.

"I think we're in the mentality that we're going to try to outscore them, or if we make a mistake offensively, we kind of let down defensively. It just all seems to snowball on us."

Richard Hamilton scored 14 of his game-high 28 points in the third quarter for the Pistons, who led the entire game and improved to an NBA-best 21-3.

Diogu scored 13 in the fourth to keep the Warriors close. He was Golden State's only effective offensive option most of the night.

He was 13-for-15 from the floor and relegated starting center Adonal Foyle to 13 minutes of action and a prime seat on the bench.

"We were just kind of tired of missing, fumbling balls that were layups, so we wanted to give Ike achance in there, see what he could do," Montgomery said. "Ike will catch the ball. He started having some success, so we stayed with him, and the guys had confidence in him, and he played well."

Foyle missed four layups or tip-ins in the first quarter and finished with two points and six rebounds.

Diogu had seven total points in 17 minutes in the first four games of the trip. He had that many by halftime Friday.

"After I scored a few points, they were looking down there for me, and I got more comfortable," Diogu said. "I felt pretty good out there today."

Montgomery said Diogu's performance may have earned the rookie steady playing time.

"I certainly hope so, but you never really know," Diogu said. "It definitely feels good, because you want a chance to play against the best players in the world, to show that you belong in this league. That's what I try to do every night."

Baron Davis and Jason Richardson added 14 points each, and Troy Murphy scored 11 for Golden State, but the trio shot a combined 16-for-44 (36 percent) from the field.

Ben Wallace had 15 points and 14 rebounds for the Pistons, and Rasheed Wallace, playing less than 24 hours after his cousin was shot and killed in a shootout with Philadelphia police, scored 19.

Rasheed Wallace did not speak with the media before or after the game.

"When he came in, I talked to him and asked him how he was and said that whatever he needs, we're here for support," Pistons coach Flip Saunders said. "He was somewhat emotional. It's a tough situation and one of the reasons I played him a lot. I thought it was better for him to be occupied than to just sit and think." chance in there, see what he could do," Montgomery said.
