BOSTON – The way things have gone on the road lately for the New Orleans Hornets, it didn’t figure they would watch one of the NBA’s most prolific 3-point shooters rim out a shot before escaping with a victory.

Trevor Ariza made a tiebreaking 3-pointer with 1:34 to play and David West scored four of his 19 points in the final minute Friday, helping the Hornets pull out an 83-81 win over the injury-riddled Boston Celtics when Ray Allen’s 3-pointer missed in the closing seconds.

“I just think we did a great job of getting stops when we needed to,” Chris Paul of the Hornets said. “Trevor hit a timely 3 right there at the end when we didn’t have anything going for us. It said a lot about us to get a stop there at the end when we were up two.”

Paul had 20 points and 11 assists for New Orleans, which won for just the third time in seven games. Emeka Okafor had 18 points and 13 rebounds.

New Orleans had lost seven straight and 9 of 10 on the road.

Ray Allen led Boston with 18 points, Paul Pierce had 12 points and seven boards, and Nate Robinson scored 11 and had six rebounds.

“I told the guys after the game that I’m not happy, we should have won the game,” Boston Coach Doc Rivers said.

Boston has lost 3 of 4 since winning 14 straight.

Celtics point guard Rajon Rondo, who leads the league with 13.8 assists per game, missed his seventh straight with a sprained left ankle.

Forward Kevin Garnett was out with a strained right calf, an injury sustained Wednesday against Detroit. Center Kendrick Perkins hasn’t played yet this season due to offseason knee surgery from an injury in Game 6 of the NBA finals and backup point guard Delonte West missed his 16th straight game with a broken right wrist.

“Obviously they’re a different team without those guys but it’s a good win for us,” Paul said.

After Boston moved ahead 73-66 on Allen’s 3-pointer with just under 6½ minutes to play, New Orleans scored 11 of the next 13 points, taking the lead on Marco Belinelli’s jumper from the top of the key with 3:07 left.

“We’ve just got to build on this one,” West said. “This is a good win for us. We haven’t won on the road in a while. It just feels good to get one.”

Robinson tied it with a driving basket with 1:59 to go. He was fouled on the play but missed the free throw before Ariza’s 3 moved the Hornets ahead 25 seconds later. West then nailed a jumper from the left wing with 54 seconds left.

Pierce had a basket and Allen hit two free throws, closing it to 82-81 with 21 seconds to play.

Boston had to foul, putting West on the line with 19.6 seconds left. He missed the first but made the second.

After Pierce fumbled a pass near the sideline, he passed it to Allen, who was forced to take his long 3. Paul grabbed the rebound and Boston was unable to foul before time expired.

“Regardless of the injuries, we’ve still got to show up and play,” Pierce said. “There’s no moral victories. It was a game of ups and downs. We just didn’t play consistent basketball.”

New Orleans opened a 66-57 lead on Okafor’s dunk in the closing minute of the third quarter before Boston scored 16 straight points over a 5:37 stretch.

Allen started the run with a jumper with four seconds left in the third and hit three straight baskets in the fourth — the final two were 3-pointers 1:15 apart. The second gave Boston a 73-66 lead with 6:27 to play.

“When you play this team here, you not only need big plays, but you have to be poised,” New Orleans Coach Monty Williams said. “I thought when they made that run in the fourth quarter, I thought our guys were poised.”
