The Miami Heat Beat the Charlotte Bobcats, 129-90

Chris Bosh scored 20 of his 24 points in the first half, and the Miami Heat improved to 5-0 for the first time in franchise history by rolling past the Charlotte Bobcats 129-90 on Sunday night.

The 129 points is the most scored by any NBA team so far this season and the 39-point victory margin matched the third-largest in Heat history. Dwyane Wade scored 22 points and LeBron James and Mario Chalmers each scored 16 for the Heat, who ran out to an 18-point lead after one quarter and never trailed.

DJ White scored 21 points and Kemba Walker finished with 17 for Charlotte, which lost its seventh straight regular-season meeting against Miami.

The Heat needed a game-winner from Wade with 2.9 seconds left to win at Charlotte on Wednesday night.

No drama required this time. In fact, it took a falling-down 3-pointer from Walker — while getting fouled — with 3:26 left to get Charlotte back within 40 points.

White made all eight of his shots in the first half for the Bobcats. The rest of Charlotte's starters in the first 24 minutes shot a staggering 3 for 22, including an 0 for 7 from D.J. Augustin and 0 for 6 from Corey Maggette.

So in control was Miami that James — who got engaged to longtime girlfriend Savannah Brinson as his New Year's highlight — wasn't even an offensive factor in the first half. His first field goal of the game came on a layup with 48 seconds remaining before intermission, and by then the Heat lead was 63-37.

Bosh controlled the play early, scoring nine of Miami's first 15 points, the last of those being an alley-oop dunk off a feed from Chalmers for an 11-point Heat lead. And with that, it was a total turnaround from the game in Charlotte last week, where Miami quickly got into an 11-0 hole and needed to scratch and claw all the way to the finish.

On Sunday, Heat coach Erik Spoelstra had the luxury of giving his starters plenty of time off in the fourth quarter, with the added bonus there being a few extra minutes to rest up for a visit from Atlanta (3-1) on Monday night.

Before the game, Charlotte coach Paul Silas said he thought Walker was "a little tired" as the rookie got used to the NBA grind.

Walker might not have been alone with that issue.

Besides White, no other Charlotte starter reached double figures in scoring. Maggette is now 1-for-16 shooting in two games against Miami this season.

Augustin finished 1 for 11, the worst shooting night of his career when trying at least 10 shots. Combined, Charlotte's starters grabbed 14 rebounds, which was four more than what Bosh collected by himself.
