After surviving a scare in Game Two at home, the top-seeded Suns had their breakneck offense back in high gear and can complete their first postseason sweep in 10 years with a win Sunday over the eighth-seeded Grizzlies.

"It is now in our control," said Suns forward Shawn Marion, who had 14 points and 13 rebounds. "We have to close it out."

The Suns toyed with the Grizzlies as they posted their largest win of the lopsided series. Quarterbacked by MVP candidate Steve Nash, they committed just five turnovers, a franchise playoff record.

Stoudemire was unstoppable, making 11-of-19 shots. He scored 11 points in the first quarter, when the Suns erased a nine-point deficit; eight in the second, when Phoenix took control; and nine more in the third, when the Suns turned it into a rout.

"I came out with 100 percent effort," Stoudemire said. "I'm just trying to be a playmaker for my team."

"His aggressiveness scares a lot of people," Grizzlies guard Bonzi Wells said. "He's just too mean for our team."

Back on its home floor, Memphis jumped to leads of 8-0 and 24-15 but put up very little fight thereafter. The Grizzlies trailed, 57-47, at halftime and never got within single digits in the second half.

"I thought that after the first quarter, we looked up at the score and saw that we were down after shooting 63 percent," Grizzlies coach Mike Fratello said. "We didn't play with the same energy after that, and Phoenix dominated the rest of the game."

"As a team, they are just on a whole different chemistry level," Grizzlies reserve guard Earl Watson said. "They're all on the same page. With us, it's like we are second-guessing everything."

The lower bowl of the sold-out FedEx Forum was almost empty when the final horn sounded and dropped the Grizzlies to 0-7 all-time in the postseason - the worst start in league history.

"This is very frustrating," Grizzlies forward James Posey said. "To get to this point and we can't get a win, it's tough ... it's just unacceptable."

The building was a lot more boisterous when a layup by Pau Gasol made it 24-15 with 3:48 left in the first period. But two 3-pointers by Quentin Richardson fueled a 16-6 surge that closed the quarter and gave the Suns a 31-30 lead.

Nash, who had 13 points and eight assists, framed a 9-0 surge with jumpers for a 44-34 bulge midway through the second quarter. Stoudemire silenced the fans during the run with a jaw-dropping dunk over Stromile Swiftwith 6:58 left in the quarter.

"We were pumped up about (the dunk)," Marion said. "That's the kind of thing that changes the momentum of the game."

"I can talk about him all day," Suns coach Mike D'Antoni said. "Some of the dunks and shots he made, he had two or three highlight reels tonight."

After a basket by Wright, Stoudemire scored inside again and Jim Jackson sank a three-pointer to push the lead to 15 points.

A layup by Richardson capped an 8-2 surge that opened the second half and gave the Suns a 65-49 lead. Phoenix held an 83-67 advantage entering the final period and cruised home.

"We're playing very poised," Stoudemire said. "They've been trying to get physical and get in our heads, but we're a very relaxed team, we understand the game, and we've been getting the wins. ... I think that just took their hearts."

"If we play like that, we feel pretty confident against most teams," Nash said. "We just have to focus on our defense. The toughest thing in sports is to close teams out, but if we put our heads together defensively, we can really separate ourselves."

Joe Johnson scored 20 points and Jim Jackson added 17 off the bench, including five 3-pointers for Phoenix, which shot 52 percent (43-of-82) and 11-of-19 from the arc. The Suns are averaging 110.7 points in this series, more than their league-leading regular-season norm.

Wright led Memphis with 14 points. The Grizzlies have had only two 20-point scorers in the series, both in Game Two.
