Sluggish at times offensively, the high-octane Phoenix Suns unveiled a new wrinkle.
Zone defense, of all things, kept the Suns unbeaten.
Steve Nash scored 25 of his 30 points in the second half, added eight assists and the visiting Suns used a dominant fourth quarter to beat the Miami Heat, 104-96, in a matchup of NBA unbeatens last night.
"We've been working on it a little bit, but we haven't really used it much or had much success," Nash said of the zone, which Phoenix displayed in the second half for the first time this season. "I was just glad, more than surprised. It really came up well for us tonight."
Sure did: Miami shot 35 percent in the second half, 23 percent in the fourth quarter. Phoenix missed fewer shots (15) in the entire second half than the Heat did (18) in the final 11 1/2 minutes.
Amare Stoudemire finished with 16 points and 11 rebounds for Phoenix, which overcame its largest deficit of the season. Jason Richardson scored 10 of his 14 points in the final period for the Suns, who are 4-0 for the first time since the 2004-05 season.
Miami got 23 points from Dwyane Wade and 18 from Quentin Richardson. The Heat (3-1) was bidding for its first 4-0 start in 5 years.
"The zone changed our rhythm," Heat coach Erik Spoelstra said. "We didn't have a lot of answers for that."
After the game, the Suns' zone drew a bit of ire in the Heat locker room.
"I thought the zone was for college, personally," Quentin Richardson said. "I thought that was the difference between the NBA and college."
