BOSTON — Kevin Garnett played much better in the 1,000th game of his career than in his first of this season.

Boston's intense leader had 18 points and 10 rebounds three days after a mediocre season opener and became the youngest player in NBA history to play in 1,000 regular-season games when the Celtics beat the Chicago Bulls, 96-80, last night.

"It feels crazy," Garnett said. "To sit here and have a plateau with 1,000 games says a lot not only about my conditioning, but, through knocking on wood countless times, taking care of my body and trying to be the best player that I can be."

Garnett reached the 1,000-game mark at the age of 32 years, 165 days — three days before the 13th anniversary of his NBA debut with Minnesota when he scored eight points, but made all four shots, as a substitute. He broke the record of 33 years, 24 days set by Shawn Kemp on Dec. 20, 2002.

Kobe Bryant is two years and three months younger and already has played 868 games. And LeBron James is already up to 393 games and won't turn 24 until Dec. 30.

"That's amazing," Boston coach Doc Rivers said of Garnett's record. "I'm assuming Kobe will break the record and LeBron will break the record, but it's nice to have."

So is a 2-0 record this season after the Celtics' 17th championship banner was raised before Tuesday night's 90-85 win over James' Cleveland Cavaliers. Garnett scored just 11 points on 5-for-15 shooting in that game.

"Tonight I felt a lot more poised," he said after making 7 of 11 shots.

This one was much easier as Boston's active defense from the start held Chicago to 4-of-23 shooting in the first quarter.

Rookie point guard Derrick Rose, the top pick in the NBA draft, led the Bulls with 18 points.
