The San Antonio Spurs preserved their 100 per cent record, while Kevin Durant starred for the Golden State Warriors.
Sunday saw the Spurs make it four wins from as many NBA games with a 106-99 victory over the Miami Heat.
Despite the absence of LaMarcus Aldridge and Danny Green, the Spurs maintained their perfect record thanks to another impressive Kawhi Leonard display.
Durant is right at home in Golden State after leading the Warriors past the winless Phoenix Suns 106-100.
After 38 minutes of action, Durant posted a game-high 37 points.
The Los Angeles Clippers held firm to beat the Utah Jazz 88-75, while the Detroit Pistons and the Oklahoma City Thunder also triumphed.
WHITESIDE NOT ENOUGH TO SINK SPURS
Heat centre Hassan Whiteside erupted on Sunday, recording a double-double.
Whiteside finished with an equal-high 27 points and 15 rebounds.
But his effort was still not enough to condemn San Antonio to their first loss of the season.
The Spurs were led by Leonard's 27 points in Miami.
DURANT PROVING HIS WORTH
The Warriors hit the headlines when they acquired Durant from the Thunder as a free agent in the off-season.
Durant, however, has not disappointed since making the high-profile move. After posting a combined 57 points in his first games, the 2014 NBA MVP scored 37 points against the Suns.
And his exploits do not appear to be hindering two-time reigning MVP Steph Curry, who added 28 points of his own for Golden State's second win of the season.
SHOE OR NO SHOE, DURANT DOES IT ALL, MANU TURNS BACK CLOCK
WESTBROOK'S THE TRIPLE-DOUBLE KING
Coming off a 51-point triple-double against the Suns on Friday, Russell Westbrook was at it again on Sunday.
Westbrook scored 33 points, tallied 16 assists and 12 rebounds as the Thunder accounted for the Los Angeles Lakers 113-96.
DRUMMOND INSPIRES PISTONS
Andre Drummond put up 20 points and 23 rebounds in a mammoth display to power the Pistons to a 98-83 victory over the Milwaukee Bucks.
The Memphis Grizzlies edged the Washington Wizards 112-103 in overtime, while the Dallas Mavericks lost 93-92 to the Houston Rockets.
BULLS, HAWKS BID TO STAY PERFECT
The unbeaten Chicago Bulls (2-0) are on the road against the Brooklyn Nets on Monday, while the Atlanta Hawks (2-0) host the Sacramento Kings.
