Leandro Barbosa scored 29 points and the Suns beat the Mavericks for the second time in 18 days, 126-104 today.

Amare Stoudemire added 24 points and Steve Nash had 23 and 11 assists as the Suns snapped Dallas' nine-game winning streak and finished their season series with the Mavs 2-2. After a scoreless first quarter, Shawn Marion had 20 points on 8-for-10 shooting. He also frustrated Dallas' Dirk Nowitzki all afternoon.

The Suns shot 65 percent (46-of-71), a record for any team at US Airways Center, formerly America West Arena. It was by far the highest percentage allowed by the Mavericks this season.

Stoudemire, who scored 41 in the Suns' come-from-behind 129-127 double-overtime victory at Dallas on March 14, made 10-of-13 shots today. In the last two games against the Mavericks, Stoudemire was 26-of-32 from the field.

Josh Howard scored 28 for Dallas, 18 in a tight first half that featured 13 ties and nine lead changes. Jerry Stackhouse added 25 and Jason Terry 20.

Nowitzki scored 21 but was just 6-of-18 shooting.

Boris Diaw had 16 points for Phoenix, and a spectacular behind-the-back bounce pass to Stoudemire for a layup.

Phoenix took the lead for good in the third quarter, then turned it into a runaway in the fourth. The 126 points were the most Dallas has allowed this season in a game that didn't go into overtime. The only time the Mavericks allowed more in any game was in that double-overtime loss to Phoenix. The Mavericks were without center Erick Dampier, who strained his right shoulder in Friday night's home victory over New York.

After making their first seven 3-pointers, the Mavericks went 2-for-11. The Suns, meanwhile, made 12-of-21 3s, 6-of-7 in the second half.

The tight, high-speed first half ended with Phoenix on top 60-56. Dallas never led after that.
