MIAMI, Nov. 23 (Ticker) -- Dwyane Wade made sure to protect the home-court advantage at American Airlines Arena.

Miami opened a 52-45 halftime lead behind 10 points from Wade, who collected his sixth double-double this season.

"Anytime we get a win, we're thankful for the outcome," said Wade, who added four assists. "It was good to see guys back out there. It was a good win tonight."

The Heat limited the Trail Blazers to just 12 points in the third period, when Wade and fellow guard Jason Williams combined for all but one of Miami's 20 points.

"Those guys both played very well, " Miami coach Stan Van Gundy said. "Very few turnovers tonight. It was an efficient game for both of them."

"We knew that this was a good pick-and-roll team, but we didn't know until today that Williams was going to play," Portland coach Nate McMillan said. "We knew Wade would be involved in a lot of pick-and-rolls, and with Williams being able to create problems in that high pick-and-roll, it really spaces the floor and forces us to come out. It's a tough two-man game to defend."

Making his first start after missing two games with a bruised knee, Williams scored 11 of his 16 in the third period.

"I was glad to see Jason come back and be as aggressive as he was in the three games before he went out," Van Gundy said.

"Jason's just being more aggressive," Wade said. "I think now, he's understanding the role he needs to play on the team, and that's shoot open shots. We're just comfortable with each other in the backcourt."

James Posey scored 12 points and Alonzo Mourning had 10 and three blocked shots for Miami, which is 6-1 at home this season. Antoine Walker scored 12 points on 5-of-10 from the field.

The Heat made 9-of-16 3-pointers and outscored the Blazers in the paint, 44-24.

Darius Miles scored 19 points and Zach Randolph added 16 and eight rebounds for Portland, which was coming off Tuesday's win at Memphis. Teenage rookie Martell Webster scored 13 points off the bench.

"I thought we got muscled tonight," McMillan said. "They pushed us around for four quarters and just dominated. They looked like the fresher team."
