BOSTON (AP) -- Paul Pierce kept Boston in the game with his scoring, but it was his pass that allowed the Celtics to earn their first victory of the season.
"It was the easiest shot I had all night," said West, who had missed seven of his previous nine shots. "That was a gimme. I had to hit that."
Pierce drove the lane with time winding down and kicked the ball to a wide-open West, who knocked down a 20-footer.
"In past years I would have maybe taken a bad shot or tried to go through people," Pierce said. "Once I saw they collapsed on me, I needed to trust my teammates. That is what better players in this league do."
Gomes had 10 points, 12 rebounds and a career-high 10 assists for the Celtics.
"I don't even think I had a triple-double at Providence, maybe in high school," Gomes said.
Brevin Knight, who finished with 22 points, missed a jumper with 7.6 seconds left in overtime for the Bobcats, who are 0-5 in Boston.
"When a great player makes the correct play, and another good player knocks down the shot, you tip your hat and move on," Knight said.
Pierce's 18-foot jumper as regulation time expired clanked off the side of the rim.
Emeka Okafor continued his strong comeback after playing in only 26 games last season with 28 points and a career-high 18 rebounds.
"You can sing the whole song about how we fought, but we want the win," Okafor said. "We've done this enough times."
