MEMPHIS, Tenn. — Sam Dekker made his first career start a memorable one.

Dekker, subbing for the ill Ryan Anderson, scored a career-high 30 points, James Harden added 29 points and 10 assists and the Houston Rockets leaned on their usual 3-point offence to beat the Memphis Grizzlies 119-95 on Saturday night.

Dekker, in his second year out of Wisconsin, said he didn't prepare for the game any differently knowing he would be on the court for the tip. And the opening showed there wasn't any nervousness.

Dekker connected on his first five shots before finishing the night 12 of 19, including 6 of 11 from outside the arc.

"I did feel very comfortable from the jump and felt very locked in," Dekker said when asked about butterflies, later adding: "When your first few go in, it really puts you at ease and (you) just kind of think everything is going to go in after that."

Eric Gordon added 21 points as the Rockets built the lead to 20 midway through the fourth and eventually 26 in coasting home.

Marc Gasol scored 32 points and Mike Conley added 15 for the Grizzlies, who lost for the third time in the last four.

"Our brains were gone," Memphis coach David Fizdale said of his team's offence. "We couldn't stop them, so offensively, we were going down."

Houston shot 51 per cent overall and 38 per cent from distance.

"We had open shots, and we were able to knock them down," said Harden, who finished 7 of 9 from the field and 4 of 6 from 3-point range.

The Rockets' aggressive defence gummed up Memphis' offensive flow. Houston defenders double-teamed Memphis and closed out on jumpers. The Grizzlies struggled shooting the entire night, finishing at 37 per cent.

Houston took the lead in the first half and never really let up the rest of the night in bouncing back from a home loss to Golden State on Friday.

By the third quarter, the Rockets stretched a 58-49 lead to a 91-72 advantage entering the fourth as Dekker steadily paced the Houston offence.

"He played well. He played really well," Rockets coach Mike D'Antoni said. "He hit the 3s that we needed. . Really good game for him."

BACK-TO-BACKS

ONE FOR THE MEMORY BANK

"I think I'll remember that my first career start was in Memphis the rest of my life," Dekker said. "That's something you always dream about doing, regardless of the circumstance. I just tried to take advantage of it and happened to have a good night."

HOLD ON THERE, YOUNGSTER

Ah, but even with Dekker's successful first start, the role is only temporary. "I think he knows what he needs to do, and he's doing it," D'Antoni said. "Now, we'll throw him back on the bench because Ryan will be back next game."
