HOUSTON, Jan. 5 (Ticker) -- On a team with a lot of weapons, Shawn Marion fired last.

Marion scored 13 of his 22 points in the fourth quarter and led six players in double figures as the Phoenix Suns defeated the Houston Rockets, 108-98.

"We've been doing this all year," Marion said. "Steve (Nash) has been getting everybody the ball and we've been able to put up the points. There's no answer for a team when they're scoring fast in transition."

The Suns raised their record to a league-best 28-4 and reached the century mark for the 27th time in 32 games.

"I've never seen a team that keeps you back on your heels when you make a shot," Rockets guard Tracy McGrady said. "I'm talking about every time you make a basket, and we're not used to that. Those guys get the ball out and they're gone."

Joe Johnson scored 11 of his 17 points in the opening quarter and helped the Suns go on a 22-8 run to open the game. They never trailed thereafter.

Amare Stoudemire scored 19 points, Quentin Richardson added 18 and 14 rebounds and Steve Nash dished out 13 assists for Phoenix, which made 15 3-pointers - one short of a franchise record - and improved to 14-2 on the road.

"You can go right down the list as everyone on the team contributed to the win," Phoenix coach Mike D'Antoni said. "They held us to less than we normally score. But we just played a very good game and shot the ball well."

Houston closed to 74-71 on Bob Sura's layup with 4:28 remaining but could get no closer as Phoenix scored 14 of the next 18 points.

Stoudemire was one reason why the Rockets could never pose a serious threat.

"We played pretty good from the start," Stoudemire said. "Joe Johnson and Quentin Richardson were really big for us on crashing the boards. We had to really focus after coming off a back-to-back and we stuck to our strategy."

McGrady led the Rockets with 24 points but missed 11 consecutive shots until he hit a layup with 5:52 left and Houston trailing, 97-84.

D'Antoni's defensive strategy to slow McGrady worked almost to perfection.

"Joe and Shawn did a good job defensively," D'Antoni said. "We didn't want to foul him (McGrady) and put him on the free-throw line. He is too good of a player to try and trick him."

McGrady wasn't too discouraged by the loss, which ended Houston's three-game winning streak.

"There's no need for us to hang our heads," McGrady said. "We played pretty well tonight. Things just didn't go our way."
