MIAMI, Nov. 12 (Ticker) -- The Miami Heat were sloppy, but good on Saturday night.

Jason Williams scored a season-high 22 points as the Heat built a huge lead en route to a 108-99 victory over the Charlotte Bobcats.

In his first season as the Heat's point guard, Williams has already been involved in a loud on-court disagreement regarding movement on offense with forward Antoine Walker.

Williams had the offense in high gear as the Heat shot 56 percent (22-of-39) in the first half in building a comfortable 57-43 lead. The lead ballooned to as many as 28 points in the fourth quarter before the Bobcats used a late run to make the final score respectable.

"I just think it's pretty simple. The shots are going in," said Williams, who made 8-of-14 from the floor. "I'm maybe a little bit more aggressive on the pick-and-roll. I'm really looking to shoot a little bit more now."

"I loved his aggressiveness tonight," Heat coach Stan Van Gundy said. "On pick-and-rolls he's one of the toughest guy in the league to contain. Now, he's starting to take it all the way to the basket. He's shooting the ball well because he's not hesitating."

But despite putting together consecutive wins for the first time this season, the Heat also showed their offense still needs work. They were able to overcome 27 turnovers that the Bobcats turned into 36 points.

"It was by far our best game of the year, but the turnovers were still too high tonight," Van Gundy said. "We've got to work on it and hold guys accountable. ... We got up by 28 points tonight, which was great. We absolutely dominated the glass."

Van Gundy also was upset that the Bobcats were using a full-court press when the game was out of hand.

"The last couple of minutes we had a 24-point lead," Van Gundy said. "I am mad at myself. I will never let somebody do that again. If they are going to press, I will leave my best players in the game and we'll win by 40."

Continuing to man the middle in place of injured superstar Shaquille O'Neal, Alonzo Mourning added 16 points on 6-of-7 shooting for the Heat, who shot 57 percent (42-of-74) and held an astounding 56-28 rebounding advantage.

Mourning turned an ankle in the third quarter and was limping in the locker room, although Van Gundy indicated the injury is not serious.

Rookie Sean May scored a season-high 18 points and Kareem Rush added 15 for Charlotte, which had 20 steals.

"My hat's off to Miami. They played one heck of a game," Charlotte coach Bernie Bickerstaff said. "This was a blowout basketball game, but we didn't surrender. We got something out of it."

"That was an outstanding performance by their team," Rush said. "We made a strong push toward the end and that made the (final) score respectable, but they clearly outplayed us."

Dwyane Wade added 19 points for the Heat, who took control of the game with a 20-5 run in the second quarter than opened a 55-37 lead.

"It was probably our best effort of the year," Wade said.
