TORONTO -- Asked how much he wanted some fruitless fourth-quarter possessions back, Stephen Curry said, "all of them."
Curry led the Warriors with 34 points and seven assists, but he also committed four of his six turnovers in the fourth quarter as the Warriors gave up a late lead and lost 104-98 to the Toronto Raptors on Sunday.
The setback, in the estimation of coach Mark Jackson, fell into the "bad loss" category.
"Steph is good enough no matter what defense he's seeing to not leave here with six turnovers," Jackson said. "He knows he's got to be better."
The Warriors led 86-81 before the Raptors went on an 11-0 run. Curry had a bad pass during that stretch, and after one of his missed 3-pointers, the Raptors' Patrick Patterson nailed one from long range to give Toronto the lead for good.
The Warriors couldn't get stops on defense in crunchtime, and with the Warriors trailing, Curry had turnovers on consecutive possessions.
"I just thought at times their energy was better than ours in the fourth quarter," said Warriors forward David Lee, who had 20 points and 11 rebounds. "That's the tough part about playing on the road."
DeMar DeRozan led Toronto with 32 points, including 12 in the fourth as the Raptors shot 48.1 percent from the field in a game that included 21 lead changes. He added six assists, and Kyle Lowry had 13 points and eight assists.
The Raptors also got contributions from Patterson and Greivis Vasquez, who scored 12 points apiece. Patterson hit two backbreaking fourth-quarter 3-pointers. The Warriors led by as many as eight points in the second quarter, but Vasquez came off the bench to score 10 straight Toronto points.
In the fourth, Golden State led by as many as six with 9:30 left. Jackson said the defense wasn't able to close out possessions while on offense there was a little too much unselfishness down the stretch in trying to do too much to spread around the ball.
Curry, who finished 13 for 27 from the field, said the turnovers were "frustrating" given that on one play he stepped out of bounds and on another had the ball go off his foot.
"We just lost our composure on the offensive end a little bit, and just didn't play solid enough on either end in the last five minutes," he said.
The Warriors, who entered the game having won five of their previous six games, fell to 2-2 on their current six-game trip and will need to win out in order to have a winning trip.
"That's the only thing you can worry about at this point, 2-0," Curry said of the team's mindset as it heads to Indiana and Boston next.
Klay Thompson added 12 points but was 4 for 15 from the field and limited by foul trouble. Harrison Barnes had 11 points off the bench.
Andrew Bogut had four points and 10 rebounds while contending with Jonas Valanciunas (10 points) as the Warriors were missing reserve center Jermaine O'Neal.
O'Neal did not travel with the team to Toronto and was unavailable for the game because of a passport that was missing until Saturday afternoon, according to Jackson.
"We thought we had it, so the ball was dropped, and we don't know whether it was stolen or lost, what have you," Jackson said.
O'Neal, who in six games since the All-Star break averaged 11.3 points and eight rebounds, tweeted that he did not leave behind or lose the passport himself. He is expected to rejoin the team in Indiana for its game Tuesday against the Eastern Conference standings leader.
"And believe me when I tell you that there isn't a person in the country more upset than me about not being able to be with my team tonight," O'Neal wrote.
