The Houston Rockets stayed hot by thrashing the Los Angeles Lakers, while the Portland Trail Blazers upstaged the San Antonio Spurs.
James Harden had his 17th triple-double of the NBA season as the Rockets made it three successive wins with a 139-100 victory at home to the Lakers on Wednesday.
Damian Lillard inspired the Trail Blazers to a 110-106 win on the road against the Spurs, who welcomed back LaMarcus Aldridge.
The Boston Celtics were also among the winners after seeing off the Minnesota Timberwolves 117-104.
WILLIAMS STARS AGAINST FORMER TEAM
Harden put up 18 points, 13 assists and 12 rebounds but Lou Williams stole the show against the Lakers.
Williams swapped Los Angeles for Houston last month as Corey Brewer was sent in the other direction, and the guard haunted his former team with 30 points.
He was seven-for-nine from three-point range, including four successive shots from beyond the arc.
ALDRIDGE RETURNS BUT SPURS LOSE
All-Star forward Aldridge was approved to return, having missed back-to-back games due to a minor heart arrhythmia.
But the Trail Blazers - coming off a 23-point loss on Tuesday - spoiled the party following Lillard's 36 points.
Aldridge finished with 19 points and seven rebounds for the Spurs, who had won 11 of their past 12 matches heading into the contest, while Kawhi Leonard had 34 points.
CELTICS STAY CLEAR
Isaiah Thomas posted 27 points as the Celtics stayed one and a half games clear of the Washington Wizards for the second seed in the Eastern Conference.
Al Horford added 20 points for the Celtics, who extended their winning streak at home to the Timberwolves to 11 games.
