(NEWS CENTER/AP)-- New Orleans Hornets rookie Austin Rivers sank a layup and ran past the Boston Celtics' bench on his way back down the floor. Doc Rivers had to fight his fatherly instinct and ignore him.
"I was about to say something. I caught myself," the Celtics coach said after facing his son for the first time. "It's a strange dynamic. I didn't enjoy it. I know it's neat for everyone else."
Greivis Vasquez had 15 points and 11 rebounds and Austin Rivers won his first NBA game against his father on Wednesday night as the Hornets beat Boston 90-78. New Orleans has won six of its past seven games to escape the Western Conference cellar.
"I knew it was a different game and I didn't try to pretend like it wasn't, and I think that helped me," the younger Rivers said. "Now that this is out of the way, it will be a lot easier. I can just go out there and not worry about, 'Oh man, this is weird.' "
Paul Pierce scored 12 points with 10 rebounds before fouling out in the final minutes as the Celtics' six-game winning streak came to an end. Kevin Garnett scored 15 and Rajon Rondo had 11 assists.
Pierce shot 5 of 16 from the floor and made one of seven 3-point attempts as Boston went 4 of 18 from beyond the arc.
