MIAMI, Nov. 28 (Ticker) -- Dwyane Wade and James Posey gave the Miami Heat much needed momentum heading into a long road trip.

Wade tied his season high with 33 points and Posey connected on five 3-pointers en route to a campaign-best 19-point effort as the Heat rolled to a 107-94 triumph over the New York Knicks.

Taking the role of team leader with Shaquille O'Neal sidelined with a sprained ankle, Wade scored 23 points in the first half for Miami, which never trailed.

"I take a lot on myself," Wade said. "I think it all starts with me. So I tried to come out tonight and attack. Hopefully, my guys follow, and they did."

"It's to our advantage that he does score the ball at a high level every night," Heat center Alonzo Mourning said. "We've got to continue to try to help him across the board."

Miami is just 1-4 away from AmericanAirlines Arena and with a five-game road swing looming (including contests against San Antonio and the Los Angeles Clippers), the team needed to halt its two-game slide.

"After losing two games in a row, to get a good win at home convincingly was good for us, especially going onto the road," Wade said. "We've got confidence."

Wade got off to a hot start in the first quarter by scoring 12 points while Jason Williams scored nine of his 18 points in the opening session as the Heat built a 29-20 lead.

"I really liked the way we came out," said Miami coach Stan Van Gundy, whose team also hit a season-high 30 free throws. "We came out with energy, and we sustained it throughout the entire first half."

"We came out early, hard from the start," said Wade, who was 15-of-18 from the line. "We didn't want to give a team any confidence in our building, so we tried to come out early, jump on them."

Mourning, who tied his club record by blocking nine shots, set the tone for the second quarter by consistently denying the Knicks on the low block, setting up numerous chances for Miami in transition. The Heat scored seven of their 14 fast-break points in the quarter.

"I try to do the best I can to block the shot and keep the ball in play so we have an opportunity to get it and capitalize on it," said Mourning, who leads the NBA with 58 blocks. "I've been doing this ever since high school."

"Alonzo just controlled the inside on both ends," New York coach Larry Brown said.

The easy baskets at the other end led to the Heat's red-hot 70 percent shooting (14-of-20) in the second quarter as they outscored the visitors, 36-19. The 36 points were the most in any quarter for Miami this season.

"We are not fooling anybody," New York center Antonio Davis said. "We aren't playing good defense. There are a lot of things that we aren't doing."

"I think they must have had 30-something points in the quarter," Brown said. "That's got to tell you a little about what is going on."

Posey made all three 3-point shots in the second for Miami, which scored a season-best 65 points in the first half.

"Tonight was one of those nights," Posey said. "I was open a lot and was able to hit some shots. Hopefully, that can continue."

Meanwhile, New York managed to make just 17-of-46 shots (37 percent) in the first half and trailed by no less than 22 points from the last two minutes of the second quarter to the final five minutes of the game.

"They were kicking our butts," said Knicks rookie guard Nate Robinson, who scored 16 points off the bench. "It's a learning process."

"We need to start looking in the mirror and figuring out what we need to do to make this team better," Davis said.

Stephon Marbury scored 19 points for the Knicks, who lost to the Heat for the fifth straight time.
