Coming off a franchise record-tying 62 wins, Phoenix has gotten off to a slow start, especially at home. It had dropped the first two games of a five-game homestand and was 0-3 at home for the first time in nine years.

The Suns lost late leads in their first three home games.

"We got a win at home, what more can you say?" Marion said. "We needed it, now we got to build from this, especially at home. We should be 4-0 at home, but it's a start."

D'Antoni, the reigning NBA Coach of the Year, entered Saturday stuck on 99 career wins but had his team in control early.

"We played well for awhile and for some reason we had a couple of lapses in the middle of the game this time instead of the end of the game, which is good." D'Antoni said. "When we learn to play continuously for long stretches, we will be good."

The Suns never trailed after Bell sparked an early 12-0 run with a pair of 3-pointers and a short jumper. Leandro Barbosa, who scored 19 points, had four in the final 30 seconds of the first quarter as Phoenix raced to a 35-18 lead.

Playing for the fourth time in five nights, the Warriors got within 53-47 at halftime but never were closer than five points in the second half.

"We don't want to make excuses, because you can't in this league, it's never going to change," said Golden State coach Mike Montgomery of his team's busy schedule. "But we were tired and we looked tired and we have got to figure a way not to be tired."

Troy Murphy's layup with 5:11 left in the game cut the Warriors' deficit to 89-83, but Barbosa answered with a jumper to start a 12-3 game-ending run. Steve Nash capped an 18-point, 10-assist effort with four free throws during the surge and Marion added a short jumper.

"We had great performances out of a lot of guys," Nash said. "Raja scoring and playing (defense), Leandro has given us a huge lift, Shawn (being) the usual Shawn, (Boris Diaw) has been a big factor.

"We have been coming along slowly, but here we're close."

Bell had his best offensive effort since signing with the Suns this offseason. He is shooting 51 percent (31-of-61) and has just six turnovers in six games.

"He does exactly what we thought he would do," D'Antoni said. "Raja's going to be solid, good defensively, a great teammate. He'll get on rolls where he had 20 (points) like tonight, but he could easily have 30 and he'll do that."

Baron Davis scored 23 points and Murphy and Jason Richardson combined for 31 rebounds for Golden State, which fell to 3-18 in Phoenix over the past 11 seasons.

Led by Derek Fisher and Mickael Pietrus, who scored 16 points apiece, the Warriors held a 42-18 advantage in bench points.

Aside from Davis, Murphy and Richardson, Golden State's remaining starters - Mike Dunleavy Jr. and Adonal Foyle - combined to shoot 0-of-4 in 19 combined minutes.

"We're lucky the guys off the bench came out and played well or it would have been really ugly out there," Murphy said.
