Dwyane Wade led the Miami Heat with 21 points as they took a 2-0 series lead after a 98-86 win over the Miluakee Bucks on Tuesday night.
LeBron James added 19, while Chris Bosh, Shane Battier and Chris Andersen all chipped in with 10 each as the Heat blew away their opponent in the opening minutes of the fourth quarter.
Up to then it had been a close game - the Bucks ending the third quarter with a fast break to finish the period down just three points, 68-65.
But James and the Heat came out of the traps firing on all cylinders and outscored the Bucks by 12 points in just 2 minutes and 22 seconds to start the fourth.
"We held court," Heat coach Erik Spoelstra told ESPN. "We protected it for two games. We did what we're supposed to do. And that's it."
Ersan Ilyasova added 21 points for the Bucks, while Mike Dunleavy contributed 16. But they'll be disappointed with the performances of their two star guards - Monta Ellis and Brandon Jennings combined for just 15 points.
Game 3 is in Milwaukee on Thursday night, but the omens don't look good for the Bucks. James is 10-0 when his team takes a 2-0 lead in the playoffs.
Elsewhere, the New York Knicks will take a 2-0 advantage to Boston following a 87-71 win against the Celtics, while the Denver Nuggets slipped to a 131-117 defeat to the Golden State Warriors. That series is now tied at 1-1.
