The defending champions Miami Heat brushed past the Milwaukee Bucks 110-87 in Game 1 of their first round playoff series.

LeBron James hit 27 points for the Heat, while Ray Allen added 20 from the bench. James finished with a stat line of 27 points, 10 rebounds and eight assists - two shy of a triple-double.

They led from the very first minute, and after the game James insisted all that matters was the win.

"All I care about is the win," James told ESPN. "I didn't even know my stats. I just knew that we were playing efficient offense besides the turnovers. We want to try to keep that going."

Dwyane Wade added 16 and Chris Bosh another 15 as the Heat held the Bucks to just 42 per cent shooting - Brandon Jennings was their star with 26 points.

Elsewhere, James Harden's return to Oklahoma City didn't go to the plan for the former-Arizona guard.

Kevin Durant top scored with 24 points, while Harden held down the fort with 20 for Houston but ultimately the Rockets slumped to a heavy 120-91 defeat. 

Sunday's two early games were uneventful affairs, the Indiana Pacers holding off the Atlanta Hawks to take a 107-90 victory, while the Kobe Bryant-less LA Lakers fell 91-79 to the San Antonio Spurs.

The playoffs had got underway on Saturday in New York as the Knicks, led by a rampant Carmelo Anthony, saw off the Boston Celtics 85-78 to take a 1-0 lead in the series.

Anthony, the NBA scoring champion, piled on 36 points for the Knicks.

The LA Clippers beat the Memphis Grizzlies 112-91, and the Chicago Bulls suffered a 106-89 defeat to the Brooklyn Nets as all eight home sides won their opening night game.

The closest match-up of the Game 1 round saw the Golden State Warriors travel to Denver in what promised to be a high octane match-up against the Nuggets - and it didn't disappoint.

Steph Curry, fresh from breaking the NBA three-point single-season record, tied the game in the final thirty seconds with a stunning shot from beyond the arc.

But Denver guard Andre Miller, at 37 years old, stole the show and Game One with a lay-up as time ticked away, using all of his savvy to breeze past Draymond Green and flick the ball home with just over a second left.
