Dwight Howard had 20 rebounds and 13 points, and the Orlando Magic rolled to an easy 102-87 win over the visiting Houston Rockets last night.

Howard outmuscled a Rockets team lacking size and strength in the middle with Yao Ming out for the season. The NBA's reigning defensive player of the year blocked four shots and showed how dominant he can be even on a night when he didn't have his best offensive game.

Jameer Nelson added 15 points in his first start since Nov. 16, helping the Magic win for the fifth time in six games ahead of a Christmas Day match against the Boston Celtics.

Carl Landry had 20 points and Aaron Brooks finished with 17 for the Rockets.

Although it wasn't his biggest scoring night, Howard cleaned up the glass and swatted away mistakes on the defensive end.

"I know that the only thing that is important is that if I'm blocking shots and rebounding we're going to win games," he said. "I have to do what it takes for our team to win, and that's rebounding and blocking shots. It's about trust. I tell our guys I have your back."

Howard, who has struggled for most of his career against Yao, threw down a series of dunks in the opening quarter to get the Magic off to a fast start. Orlando ended the first quarter on a 14-2 spurt highlighted by a pair of three-pointers by Ryan Anderson, taking a 34-22 lead.
