Parker scored a season-high 29 points in 30 minutes and thoroughly outplayed Nash as the Spurs snapped the Suns' 11-game winning streak with an emphatic 115-94 victory.

"I knew I had to have a lot of energy and go back at him because if you don't go back at Steve Nash, he is going to beat you every time," Parker said. "I thought in the second half, he was a little bit tired. It was a big challenge for me. Steve Nash is the best point guard in the league and is playing great. That's why you play in the NBA against the best, I love it."

Phoenix, which entered the contest with a league-best 24-3 mark and 20 wins in its last 21 games, took a 35-32 lead after one quarter behind 12 points from Nash. But the Suns fell behind by halftime, 61-54, and were outscored, 32-15, in the third quarter, with Nash failing to score in either period.

"They scored 35 in the first quarter and that's uncharacteristic for us and characteristic for them," San Antonio coach Gregg Popovich said. "After that, we talked about what our goals were and I thought Tony and Timmy (Duncan) set a good tone aggressiveness-wise, physical play and really going at it offensively and picking it up on the defensive end from that point on."

Meanwhile, Parker scored 13 points in the second quarter and 10 in the third before sitting out nearly all of the fourth with the win in hand. Parker connected on 14-of-20 shots for the Spurs, who made 52 percent (47-of-91) overall.

"They just kicked our butts," Nash said. "We had a good first quarter and they came storming back. We didn't show a lot of poise or focus tonight. But maybe that's good for this team, to face a tough challenge like this and learn from it.

"We got embarrassed, but we can use that positively. We can make this a turning point in our season. We can learn that we are not a finished product and there are a lot of things to work on and good things we can build on."

Duncan collected 16 points, 12 rebounds and six assists for San Antonio, which improved to 14-1 at home.

"It was a huge game for us," Duncan said. "We shot the ball a lot better than they did. You don't want to say it's a statement game, but we are excited about the win."

Amare Stoudemire eclipsed the 30-point mark for the fourth straight game with 37 for the Suns, who shot just under 40 percent (31-of-78). Shawn Marion was limited to six points and Quentin Richardson two.

"We just need to play some better defense, that's all," Stoudemire said. "We struggled defensively. This team, we can score all night long, but we have to man up on defense. This might be good for us. It's never fun to lose, but you have to look back at games like this and correct the mistakes you made next game."

Phoenix, which entered the contest averaging a league-high 109.3 points, had not lost by more than five this season. Nash, who had recorded at least 10 assists in each game during the Suns' winning streak and was averaging a league-best 11.2 this season, managed just four in this one.

"We just ran into a great team tonight," Phoenix coach Mike D'Antoni said. "We didn't do a good job containing Tony Parker on the pick-and-roll. They are a championship team that did what they needed to do tonight.

"We were up eight or nine at one point and then they really buckled down on defense. We let them in the paint too much and we were not clicking on offense. When you don't click against a team of this caliber, you're in trouble."
