McGrady went on a personal 9-0 run — a floater, two free throws, a driving layup and a 3-pointer — and scored 13 consecutive points for Houston as the Rockets whittled away at Utah's double-digit advantage.

And when backup point guard Bobby Jackson hit a runner with 29.4 seconds left before halftime, the Jazz lead was down to one at 55-54.

Williams, though, knocked down a 3-pointer 7.9 seconds before the half was done, sending Utah into the break up 58-54.

The Jazz point carried his hot hand into the third quarter, helping push Utah's advantage to 85-65 heading into the fourth.

"We just ran out of gas," Rockets coach Rick Adelman said. "We couldn't make another run."

Williams finished 9-of-17 from the field, including 6-for-9 from 3-point range overall and 4-of-5 from behind the long-distance line in the third quarter alone.

"I wasn't looking to score as much in the first half," Williams said, "and I wanted to be a little more assertive in the second half."

"He (Williams) was a lot more aggressive in the second half," McGrady said. "It seemed like he was feeding off the crowd."

Okur (19 points and a game-high 13 rebounds) and Boozer (15 points, 10 boards) both had double-doubles for the Jazz, who also got 13 points from Brewer, 11 from Kirilenko and 10 apiece off the bench from Matt Harpring and Kyle Korver.

McGrady, meanwhile, went scoreless with 0-of-4 field shooting during a third quarter in which Houston shot just 18.2 percent (4-for-22) and the Jazz outscored the Rockets 27-11.

"They came out ready for us," Adelman said.

"We made a game of it at halftime thanks to Tracy (McGrady), who was just unbelievable," he added. "Then they took control. You've got to give them credit. Their better players stepped up; Williams was terrific."
