HOUSTON — On a night where James Harden's shots weren't falling for three quarters, the Houston Rockets got big performances from those in supporting roles until the star stepped up late to close out the victory.

Harden scored 18 of his 34 points in the fourth quarter and Ben McLemore added 27 points to help the Rockets outlast the Phoenix Suns 115-109 on Saturday night.

Harden had a tough shooting night through three quarters and was 5 of 19 overall and 1 of 10 on 3s with 16 points before getting going in the fourth. The game was tied with about 7 minutes left, and he scored all of Houston's points in a 13-6 run that made it 102-95.

“That's how deep we are,” Harden said. “We have a really good team and guys that can make plays and knock down shots. More importantly we were focused on our defence.”

Russell Westbrook had 24 points, 14 rebounds and 11 assists for his third straight triple-double and sixth this season. Harden finished 8 of 27, 3 of 17 on 3s and made 15 of 18 free throws.

Devin Booker led the Suns with 35 points after scoring a season-high 44 in an overtime victory at New Orleans on Thursday night.

Phoenix coach Monty Williams was proud of his team for staying in it until the very end.

“We have a mentality that we just don't give in,” Williams said. “We're playing young guys that are learning how to play against physical NBA men and that's part of developing.”

The Suns cut the lead to five twice in the last 90 seconds, but both times Westbrook made a layup to extend the advantage. And the second time he was fouled on the shot and made the free throw to make it 114-106.

The Suns scored seven straight points, capped by a dunk from Kelly Oubre, to tie it at 85 with about 9 minutes left. After a timeout, Harden scored Houston's first points in about three minutes on a layup to put Houston back on top.

It was tied again before Harden scored five points to give the Rockets a 94-89 lead. He stole the ball from Ty Jerome after that and was fouled by Booker on a drive, with Harden aggressively continuing forward and pushing Booker off the court. Harden later shoved Booker, and they both received technical fouls to the bewilderment of the Suns.

Harden made both free throws to make it seven points in a row and was fouled again after he stole the ball from Mikal Bridges. Harden made one of those free throws to make it 97-89.

“He finds a way to win the game,” Houston coach Mike D'Antoni said. “A lot of guys contributed. A lot of guys played well.”
