The five-game slide is the Raptors’ (13-17) most prolonged dry spell since they dropped seven in a row to conclude the 2020-21 season.

Toronto forward Scottie Barnes added 17 points.
Siakam opened the game with back-to-back three-pointers to give the Raptors a 6-3 lead. However, that was the final time the home side would have a lead in the game.
On the strength of Green’s 13 first-quarter points, including three consecutive three-pointers, the Warriors held a 36-26 advantage after the opening frame.
Despite beginning the second with a 5-0 run, the Raptors were behind 68-54 at halftime. Poole did most of the damage with 15 points in the frame for a first-half total of 25.
Golden State enjoyed a 102-80 edge after three quarters.

Nurse also revealed Anunoby had been dealing with an unspecified illness.
“I expect him back this week, sometime,” Nurse said. “What (the medical staff) said, is he’s back and through his sickness, and both his hand and his hip are improving.”
