The loss dropped the Celtics to 20-22.
"We're two games under .500," Pierce said. There's "still a lot of season left so we believe we can climb back in this division race."
For now, the Knicks (26-14) lead that by one game over Brooklyn.
"I expected more hostility from the crowd and it wasn't as bad as I thought," Stoudemire said. "It's a rivalry game and we want to go into the All-Star break with a nice division lead."
Notes: Chandler was chosen to the Eastern Conference All-Star team on Thursday, the first selection for last year's Defensive Player of the Year. Anthony, Garnett and Rondo were all voted to start, but East coaches passed on Pierce.
