OAKLAND -- If it wasn't already clear that point guard Stephen Curry was the engine that powers the Warriors, Wednesday night's performance by Golden State proved it.
With the Miami Heat in town, the Warriors figured to have a tough time winning. With Curry on the bench in a suit, turns out they didn't stand a chance, embarrassed by the defending NBA champion 92-75 on their own court.
"One thing I told them was that they made a heck of a case for Stephen Curry to be in the All-Star game," Warriors coach Mark Jackson said after the loss.
The Heat sent Golden State to its second straight defeat and avenged a loss to the Warriors in Miami last month.
Curry missed his first game of the season after spraining his right ankle at a shootaround Wednesday.
In the first game, Miami focused most of its defensive attention on stopping Curry. With the Warriors star out Wednesday, the Heat's defense dominated. The game was over midway through the third quarter. By the time the fourth quarter started, Golden State was down 30 points.
"They're a defensive-minded club," said point guard Jarrett Jack, who started in Curry's place. "We kind of allowed them to get into a rhythm offensively by not taking care of the ball early. That's a team that makes you pay for it on the other end."
Jack was the only player who had a remotely positive effect on the game. He had 16 points on 7-of-14 shooting. But he had five turnovers and just two
David Lee -- 12 points on 4-of-13 shooting -- could get little done as the primary offensive option. Klay Thompson had more turnovers (four) than made baskets (one). Rookie Harrison Barnes had just nine points on 3 of 12.
The Warriors not only couldn't score against Miami's defense but also had trouble just getting the ball past midcourt.
"Their team had some tough moves with (Curry) not being in there," Miami coach Erik Spoelstra said. "That makes a difference."
Offense wasn't a problem for the Heat. LeBron James had 25 points, 10 assists and seven rebounds. Dwyane Wade had 15 points to go with six assists and eight rebounds. Mario Chalmers knocked down four 3-pointers en route to 15 points.
The Warriors trailed by 11 in the first quarter and entered the second quarter in OK position, down 28-21. But the Heat -- which had lost three of four and concludes its six-game trip at the Los Angeles Lakers on Thursday -- ratcheted up the intensity in the second quarter and started to pull away.
The Warriors shot just 28.6 percent from the field and kicked the ball around like the hardwood was a soccer pitch.
Back-to-back layups got Miami's lead down to 28-25. But the Heat responded by rattling off nine straight points. James started the spurt with an alley-oop to Wade. A Chalmers 3-pointer later made it 37-25 with 6:36 left in the first half. Golden State turned it over four times in a two-minute stretch to fuel the run.
The Warriors went into the locker room down 14, a good run away from making it a game. But Miami had a 13-0 run to start the third quarter. The Warriors missed their first four shots and turned it over four times over the first four minutes.
Chalmers, who made 10 3-pointers in a win over Sacramento on Saturday, knocked down two wide-open 3-pointers to open the second half. Then James dunked home a half-court alley-oop from Wade to put the Warriors down 24.
After another Chalmers 3-pointer, Golden State trailed 65-38 with 8:33 left in the third quarter.
The rest of the game was a laugher as the Warriors showed little fight.
"I've seen it from them sporadically," Jackson said of his team looking demoralized. "I've seen it from different individuals. But I haven't seen it much as a group. That was the disappointing thing."
James also passed the 5,000-assist mark when he set up Wade for a dunk in the first quarter. James is the only NBA player to reach 20,000 points, 5,000 assists and 5,000 rebounds.
"I'm doing a lot better handling it," Jenkins said of his limited role. "It's not becoming a mental thing or messing up the way I approach the game. I'm still coming in early, still leaving late. ... I'm just going to try to be as patient as possible ... just wait on my chance. That's something I did last year, and my chance came."
Jenkins, who can also fill in at shooting guard, said although his role is less he still feels like the Warriors believe in him.
"There are not many 6-foot-3 shooting guards in the NBA," Jenkins said, "so it definitely shows (Jackson) wants me out there and he believes in my game."
