OAKLAND, Calif., Jan. 28 (Ticker) -- Sam Cassell proved how valuable he is by spending too many minutes on the bench.

Cassell was hampered by foul trouble before fouling out and the Timberwolves had a five-game winning streak snapped in a 97-90 loss to the Golden State Warriors, who got 21 points and 19 rebounds from Erick Dampier.

Seeking his first All-Star berth, Cassell had a rare poor game. He was limited to 31 minutes and did not do much with them, collecting 14 points and four assists while committing seven turnovers.

"Tonight was a tough night for me personally," Cassell said. "I've got to run my ballclub better than I ran it tonight. I didn't do my job tonight. It's a team effort, but each individual has got to do their part to make us successful. I didn't do my part tonight, so I am fully responsible for the loss."

The Timberwolves got a monster performance from Kevin Garnett, who collected 20 points, 20 rebounds and 10 assists for his second triple-double of the season. But they struggled offensively without Cassell's guidance.

"Unfortunately we didn't execute like we usually do in the fourth quarter," Garnett said. "(The Warriors) outscored us in the fourth quarter and that's something that rarely happens with us."

Minnesota climbed within one four times in the final five minutes but could not contain Dampier, who had a tip-in with 2 1/2 minutes left.

Dampier made 2-of-2 free throws to give Golden State a 92-89 edge with 94 seconds to go after Cassell picked up his sixth foul. He added another free throw 18 seconds later.

"I just went out there and played," said Dampier, who also is hoping for a spot on the All-Star team. "It's the last game before the All-Stars come out, so I just wanted to have a good game tonight. The biggest thing for me was to be consistent. It's what I've been working trying to do."

The Timberwolves, who lost Troy Hudson to a sprained ankle in the third quarter, were left without a point guard, and Latrell Sprewell and Fred Hoiberg forced ill-advised 3-pointers in the final minute.

"We got into a situation where we're trying to play the last two minutes without a point guard, so we got caught," Minnesota coach Flip Saunders said. "Whoever was going to be more aggressive was going to have success and they were more aggressive in everything they did."

Sprewell scored 27 points but made just 9-of-27 shots and Garnett was held to just two free throws in the fourth quarter for Minnesota, which shot under 39 percent (34-of-88).

"We were out of sync a little bit with Sam being in foul trouble," Sprewell said. "We're doing things we hadn't been accustomed to doing so we were a little bit out of sync."

Brian Cardinal scored 21 points and Speedy Claxton added 19 for the Warriors, who have won consecutive games after losing 12 of 15.

Jason Richardson collected 17 points and 10 rebounds for shorthanded Golden State, which played without injured starters Nick Van Exel and Troy Murphy.

"Our energy level has picked up despite having only nine players able to practice," Warriors coach Eric Musselman said. "I thought their focus has been phenomenal."
