The only thing wrapped up for LeBron James' birthday was James himself.

A year after receiving a Hummer for his 18th birthday, James had a bummer of a night as he turned 19. Artest locked him up in the second half as the Indiana Pacers defeated the Cleveland Cavaliers 92-89 on Tuesday night.

``The guy is tough, but I think anybody can be stopped if you turn up your defense,'' said Artest, whose in-your-face defense against James down the stretch helped the Pacers become the first team in the league with 23 wins.

Artest scored 18 points, none bigger than his 3 with 54.6 seconds left, and Jermaine O'Neal had 21.

Elsewhere, New York routed Miami 102-73, Dallas defeated Milwaukee 101-92, Seattle topped Memphis 105-99, Minnesota beat Chicago 98-93, Toronto downed Denver 81-74 and Atlanta defeated Washington 83-73.

James finished with 22 points, 10 rebounds and four assists in 38 minutes but couldn't shake free in the fourth quarter. Cavs coach Paul Silas felt his talented rookie was intimidated.

``Artest is going to test anyone. He's grabbing and holding, and they're letting him get away with it,'' Silas said. ``But LeBron has got to push him off, stand up to him and get in his face, and say, `If you do it again, we're going to war.' LeBron is not there yet.''

James, who came in averaging 27.8 points in his last 10 games, was just 3-for-12 from the field after a 6-for-8 first quarter. He missed all four of his 3-pointers.

The Cavaliers lost their third straight to Indiana this season in part because of 18 turnovers and 10 missed free throws _ six in the fourth quarter. The Pacers have beaten the Cavaliers 11 straight times at Gund Arena and eight in a row overall.

``I love playing physical. But this is one team we can't get over the hump on,'' James said.

Knicks 102, Heat 73

At New York, Keith Van Horn had a steal and buzzer-beating dunk to cap a dominant first quarter, and the Knicks cruised the rest of the way.

New York won its fourth in a row, all the victories coming in convincing fashion. The last three victories have all been by at least 20 points, the first time New York has done that since November, 1997.

Van Horn scored 22 points, shooting 10-for-16 from the field in breaking 20 for the fifth time in six games. Shandon Anderson came off the bench to add 21.

Before the game, the Knicks acquired point guard Moochie Norris and center John Amaechi from Houston for forward Clarence Weatherspoon.

Lamar Odom led Miami with 19 points.

Mavericks 101, Bucks 92

At Dallas, Antoine Walker had 22 points and 14 rebounds, and Dirk Nowitzki made two key fourth-quarter 3-pointers to help Dallas withstand a late rally.

Steve Nash added 14 points and 12 assists, Antawn Jamison came off the bench to score 17, and Nowitzki had 20 points and 11 rebounds to help Dallas to its third straight win. The Mavericks improved to 14-2 at home.

Michael Redd led the Bucks with 25 points.

SuperSonics 105, Grizzlies 99

At Memphis, Rashard Lewis scored 33 points and Ray Allen had nine in the final three minutes.

Lewis and Allen scored Seattle's final 15 points as the SuperSonics pulled away late. Allen finished with 22 points, playing in his fourth game of the season after right ankle surgery.

The Grizzlies have lost seven straight, matching their longest losing streak under second-year coach Hubie Brown.

Timberwolves 98, Bulls 93

At Minneapolis, Kevin Garnett had 28 points and 15 rebounds to lead Minnesota to its eighth victory in nine games.

Latrell Sprewell had 27 points _ 20 in the first half _ and Sam Cassell had 21 points and nine assists for Minnesota, which beat the Bulls for the 10th straight time.

The Timberwolves held on despite blowing a 20-point first-half lead and missing nine free throws in the fourth quarter, including four straight by Garnett in the final two minutes.

Raptors 81, Nuggets 74

At Denver, Alvin Williams and Jalen Rose each had 17 points, and Williams hit four free throws in the last two minutes as Toronto snapped the Nuggets' three-game winning streak.

Carmelo Anthony had 19 points and seven rebounds for the Nuggets, who lost for only the fourth time at home.

Hawks 83, Wizards 73

At Washington, Shareef Abdur-Rahim had 25 points and 16 rebounds to help Atlanta end a nine-game road losing streak.

Stephen Jackson scored 16 points, Jason Terry added 13 and Dion Glover 10 for the Hawks, who hadn't won on the road since beating Milwaukee on Nov. 18.

Larry Hughes had 24 points for the Wizards, who have lost five in a row.
