Lakers 102, Celtics 89

Ron Artest proved it in his opening-minute scuffle with Paul Pierce, tumbling to the ground with a vise grip on the Celtics star's elbow.

Kobe Bryant emphasized it one last time with a rub-it-in 3-pointer in the waning seconds of an NBA finals opener that was already a rout.

These aren't the same Los Angeles Lakers who got pushed around by their biggest rivals on the NBA's biggest stage two years ago. They're rougher and tougher - and surprisingly willing to play the Boston Celtics' bad-tempered game.

Bryant scored 30 points, Pau Gasol had 23 points and 14 rebounds, and the defending champion Lakers did a remarkable job of the dirty work in a 102-89 victory over Boston in Game 1 on Thursday night.

Artest scored 15 points after his tangle with Pierce in the opening minute of the 12th finals meeting between the NBA's most decorated franchises. Artest and Pierce backed into each other with their elbows locked while battling for rebounding position. Both got technical fouls after they crashed to the court and got up ready to rumble.

``That's not a tone that we want to set,'' Artest claimed. ``I was a little emotional, and I had a little bit of anxiety at that point, and I was fired up.''

Yet other Lakers were grateful for the tone, and they weren't surprised Artest set it. The Lakers' defensive stopper is their only new player this season, and he quickly showed Pierce - the 2008 finals MVP - that trophies won't be quite so easy to earn against the Lakers this time.

``I knew it was going to be physical. That's a given,'' Gasol said. ``After consecutive finals, we understand the nature of the game. We understand who our rival is, how they play. You've got to compete, and you've got to match that physicality, that aspect of the game to be successful.''

The Lakers overwhelmed the Celtics in the third quarter, taking a 20-point lead with sturdy defense and a quick-strike offense. Los Angeles outrebounded the Celtics 42-31, outscored them in the paint 48-30 and put up a lofty shooting percentage until a fourth-quarter slump.

Bryant added seven rebounds and six assists to his 12th 30-point game of the postseason. Andrew Bynum scored 10 points on his injured right knee as the Lakers improved to 9-0 at home in the playoffs, with 12 straight postseason home wins dating to last year's championship run - and not many were more physical than this one.

Pierce scored 24 points and Kevin Garnett added 16 after a slow start for the Celtics, who might not want to know Lakers coach Phil Jackson's teams in Los Angeles and Chicago have won 47 straight playoff series after winning Game 1.

The Celtics were frustrated after giving up 100 points for just the second time in their last 10 games.

``They were the more physical team by far,'' Celtics coach Doc Rivers said. ``They were more aggressive. They attacked us the entire night. I didn't think we handled it very well.''

Game 2 is Sunday night at Staples Center.

While the Lakers played to their strengths, the Celtics' ostensible advantages - toughness, defense and veteran savvy - weren't so much in evidence. Rajon Rondo had 13 points - just three in the second half - and eight assists for Boston, which went 1 for 10 on 3-pointers.

``You can't ease into the game, especially in the finals,'' Pierce said. ``That's one of the better rebounding teams in the NBA. We've just got to do a better job rebounding the ball, eliminating easy opportunities. When I look up and we've given up 100 points, I haven't seen that in a while.''

Ray Allen scored 12 points in just 27 minutes, saddled with constant foul trouble while trying to guard Bryant. Pierce also picked up early fouls, while Garnett simply struggled, going 7 for 16 from the field and grabbing just four rebounds - even inexplicably missing an open layup with 5 1/2 minutes to play.

That's mostly because of Gasol, the Spanish 7-footer determined to assert himself after admittedly getting pushed around by Garnett two years ago. Gasol capped a strong game by sprinting downcourt and catching a long pass in stride for a dunk with 6:21 to play.

``Pau played a big game tonight,'' Jackson said. ``I thought they did a good job on him in the post, but his movement and his activity was important.''

After Artest and Pierce got wrapped up, the mood didn't improve much in a game featuring 54 fouls. Yet the Lakers' aggressiveness was reflected in 10 free throws apiece for Bryant and Gasol, who made 16 of them, along with steady guard penetration from Bryant, Derek Fisher and backups Jordan Farmar and Shannon Brown.

Bryant also praised the defensive effort of Artest, whose block on Glen Davis triggered the fast break that led to Gasol's dynamic dunk.

``I think he does a great job for us of setting the tone defensively with his intensity and with his energy,'' said Bryant, who greeted Artest with a hug after that block. ``I was just letting him know it was well appreciated.''

NOTES: An entertaining jump ball occurred midway through the second quarter when 5-9 Nate Robinson tied up the 7-foot Gasol. The Spaniard won the tip. ... Celtics C Kendrick Perkins didn't get his seventh technical foul of the postseason, which would have resulted in an automatic one-game suspension, but technical-foul legend Rasheed Wallace got one for arguing late in the third quarter. ... Fans near courtside included Jerry West, Leonardo DiCaprio, Charlize Theron, David Duchovny, Will Ferrell, boxer Floyd Mayweather Jr., Terrell Owens, Steven Spielberg, Snoop Dogg, Mike Epps and Hilary Swank. Chris Rock, David Spade, Kevin James and Adam Sandler sat together at courtside to promote their ``Grown Ups'' movie, opening in three weeks.
