Jamal Crawford scored a season-best 37 points and had 11 assists, and Blake Griffin scored 30 points, as the Los Angeles Clippers defeated the Toronto Raptors 126-118.
Terrence Ross led the Raptors by tying the club record with 51 points on 16-for-29 shooting including 10-for-17 from three-point range.
He missed a free throw with four seconds to play that would have erased Vince Carter's club record set in 2000.
NBA scoring leader Kevin Durant scored 32 points in the Thunder's 103-91 victory over the Philadelphia 76ers, extending to 10 his consecutive-game streak with 30 or more.
He added 14 rebounds and 10 assists for his second triple-double of the season, and the fifth of his career.
Durant, who missed Friday night's victory in Boston with a sprained right shoulder, is just the sixth NBA player since 1990 to fashion a 30-point-plus streak of 10 games or more.
He shot 12-for-17 from the floor, as the Western Conference-leading Thunder (35-10) won their seventh straight.
Technically, it was not a doubleheader sweep but the Memphis Grizzlies' 99-81 victory over Houston was their second win over the Rockets in a 24-hour span.

He hit six three-pointers, including three in the fourth quarter when the Bulls pulled away.

Forward Paul Millsap had 20 points and shooting guard Louis Williams added 18 off the bench as the short-handed Atlanta Hawks rolled to a 112-87 rout of the Milwaukee Bucks.
