OAKLAND, Calif. -- The Warriors committed 20 turnovers Wednesday night and watched the Toronto Raptors take 103 shots against them.

Golden State won anyway, even if coach Steve Kerr was not entirely happy with the means.

Klay Thompson scored 12 of his 21 points in a 42-point first quarter that helped Golden State build as much as a 25-point lead, yet the Warriors had to hold on for a 121-111 victory over the relentless Raptors.

"Strange game," Kerr said. "You have to make all of your shots, practically, to win when you are giving the other team so many more attempts."

Despite seeing a seven-game road winning streak end, the Raptors experienced a historic moment when DeMar DeRozan became the franchise's all-time leading scorer, surpassing Chris Bosh with the 15th of his team-high 29 points.

DeRozan, currently in his eighth NBA season, finished the night with 10,290 career points, 15 more than Bosh, who played his first seven seasons for Toronto.

"It's great," DeRozan said of the accomplishment. "Would've been a lot better if we got the win. But to be first in franchise history, it's definitely an honor."

Kyle Lowry recorded a 27-point, 11-assist double-double, and Terrence Ross dropped in 24 points off the bench, but it wasn't enough firepower to prevent Toronto's first loss in three games on its current six-stop trip.

Kevin Durant had a 22-point, 17-rebound double-double, and Stephen Curry poured in a team-high 28 points for the Warriors, who were coming off a 109-108 loss at Cleveland on Christmas Day.

The Warriors couldn't overcome 20 turnovers and a huge disparity in shot attempts (95-77) at Cleveland.

They barely managed to do so Wednesday despite the Raptors posting a 103-81 edge in shots.

"We've got to do better with that. We've got to rebound the ball better," Warriors forward Draymond Green said after watching the Raptors pull down 19 offensive rebounds.

"There are some things that we look out and say: All right, we need to do those things better. At the same time, you look at those positives and that first quarter was incredible. You feel good about those as well."

Green had 14 points and 10 assists for Golden State, which began a stretch of nine of 10 at home. Durant added seven assists and five blocked shots.

In the end, it wasn't easy, but Golden State (28-5) nonetheless extended its streak of not losing consecutive regular-season games to an NBA-record 119.

The first-quarter flurry, which began with a 22-4 runaway in the first 4:41, produced the game's eventual difference in Golden State's 12th straight home win over Toronto.

"A lot of energy to start the game, the ball was moving beautifully, our defense was flying around, and that's what got us that huge first-quarter lead," Kerr said. "We needed it. We needed all of it as it turned out because we couldn't sustain that pace. That first quarter was about as good a quarter as anybody will ever play."

The seesaw game saw Toronto, down by 25 at first quarter's end, pull within five in the second period, only to drop back again by as many as 20 in the third.

Playing the front end of a back-to-back, the Raptors had one burst left in them in the fourth quarter, rallying within 114-109 with 3:01 to play with a 15-2 run capped by a DeMarre Carroll layup.

However, Carroll and Ross misfired on 3-pointers with a chance to cut the deficit to two, and Curry, fouled after grabbing an offensive rebound, hit a pair of free throws with 2:04 to go, extending the Golden State lead to 116-109.

"We didn't shoot the ball extremely well on shots we normally make," Raptors coach Dwane Casey said. "We had some open shots we missed, and we needed them."

Golden State outshot Toronto 56.8 percent to 38.8 percent from the field and 60.9 percent to 37.1 percent on 3-pointers.

Carroll had 13 points for the Raptors, who play at Phoenix on Thursday night.

NOTES: The Warriors are 5-0 after a loss this season. ... Golden State's 42 first-quarter points were a season-high. ... The Warriors' 12-game home winning streak over the Raptors is tied for the franchise record. They had 12-game runs against the St. Louis Hawks from 1955-58 and the Los Angeles Lakers from 1973-77. ... As Raptors SG DeMar DeRozan approached the all-time franchise scoring lead, Toronto coach Dwane Casey said pregame: "I couldn't think of anybody who deserves that honor or record or whatever you want to call it more than DeMar. He's the face of our franchise. He represents it in a first-class way."
