A letdown in the wake of Wednesday night's victory over the Indiana Pacers? Not when there was this much fun to be had.

Not when LeBron James is turning Ben McLemore into Jason Terry in the first quarter, with a near-decapitation of a dunk that went viral in milliseconds.

Not when Ray Allen is dunking twice -- yes, you read that right -- in the first half.

Not when Shane Battier is draining multiple 3-pointers for the first time in nearly three weeks.

Letdown? Try beatdown, with the Miami Heat pushing past the Sacramento Kings 122-103 Friday night at AmericanAirlines Arena to move to 4-0 on this five-game homestand that concludes Monday against the Atlanta Hawks.

"We came in with a professional mindset and got a win," James said. "Our energy level was high."

"Just taking care of business," guard Dwyane Wade said.

"All about business," Allen said.

Coach Erik Spoelstra sensed early in the day that letdown would not be part of his team's Friday lexicon.

"I don't have any complaints with how the guys showed up today," he said of the approach at the morning shootaround. "They showed up to work. There wasn't a lot of dragging, pulling to get focused.

"It's a mature group, so they showed up with the right mindset."

And then went on to produce a Friday frenzy, their highest-scoring game of the season, eclipsing a 120-point effort in November against the Orlando Magic. The Heat closed at .614 from the field, scoring 70 points in the paint, tying for the third-highest such total in franchise history.

"We just had to put some defense in the game," center Chris Bosh said, with the Heat doing just that, limiting the Kings to 42 points in the second half after they scored 61 in the first half.
