Marbury made all six of his 3-pointers and scored 35 points as the Phoenix Suns used the long ball to defeat the San Antonio Spurs, 104-97.

Marbury, who poured in 43 in a win over the Spurs on November 29, paced the Suns' 10-of-13 effort from the arc and dished out 13 assists.

In sharp contrast was San Antonio's woeful 3-of-26 performance from 3-point range.

"We had to do whatever it took to win this game," Marbury said. "Tonight's win was the biggest game of the season, mostly due to the way we've been playing."

Marbury also did it from inside when he had to. After Tony Parker rattled home a 3-pointer with 80 seconds left to cut the deficit to 97-95, Marbury drove the lane for a layup.

Duncan, who collected 35 points, 21 rebounds, eight assists and four blocks, answered with a lay-in, but rookie Amare Stoudemire bulled in a layup over Duncan with 38 seconds to play.

"Tim is probably the best player in the league," Marbury said. "We knew he was going to get his points, we just came up with big plays when we needed them."

Phoenix padded its lead as Scott Williams hit a foul shot and Shawn Marion hit two free throws, while the Spurs failed to score the rest of the way.

The loss snapped San Antonio's five-game home winning streak.

"We're a young team, we practice hard and we play hard because we're trying to make the playoffs," said Stoudemire, who had 17 points and 11 rebounds. "Tonight we were focused and we had a great game."

Duncan carried the cold-shooting Spurs, hitting 14-of-18 from the field to lead them to a 46 percent (38-of-82) shooting night. Excluding its All-Star forward, San Antonio shot a woeful 37 percent.

"You have to give a lot of credit (to Phoenix)," Duncan said. "They fought very hard tonight. Every time we made a run at them, they came up with a big shot, or a rebound to keep us at bay. Hats off to them, they did a lot of things well tonight."

From much longer range, Marbury was even more accurate, sinking 12-of-14 shots as the Suns hit 59 percent (39-of-66) from the floor en route to just their second win in the past seven games.

Marion scored 17 points and Joe Johnson and Williams added 13 for the Suns, who are two games ahead of Houston for the final playoff spot in the West.

Marbury had the hot hand from the outset, hitting a pair of 3-pointer in the first 90 seconds as Phoenix took an 11-2 lead.

The Spurs fought back and pulled within 30-28 by the end of the quarter on Emanuel Ginobili's 3-pointer.

The Suns led by as many as 11 while remaining on top until 10:42 remained in the fourth, when Malik Rose capped a 6-1 spurt with a hoop that gave San Antonio a 73-72 edge.

That brief lead disappeared for the duration 16 seconds later when Marion drained a 3-pointer, igniting an 11-0 run capped by Stoudemire's free throw at the 8:12 mark.

"You always have to win as a team, that's how we're built," Spurs coach Gregg Popovich said. "We made some mistakes down the stretch on offense and defense. They shot very, very well."

Trailing 95-86, the Spurs went on a 6-0 run that Ginobili concluded with two free throws, but they were unable to sustain their comeback bid.

"Since the All-Star break, we haven't been playing very well against top-tier teams," Phoenix coach Frank Johnson said. "The Spurs are definitely a top-tier team, so beating them at home, it's a big win for us."

Ginobili scored 14 points, Rose and Parker each scored 13 and Stephen Jackson had 12 while shooting just 3-of-15 for the Spurs, who suffered just their second loss in the past 15 home games.
