Duncan scored 33 points, pulled down 16 rebounds and blocked three shots as the Spurs pulled away in the closing two minutes.

"I thought we did a great job of getting back (on defense)," Duncan told reporters.

"They hit some shots to keep them in the game, but all and all I thought we did a great job of getting back on them," Duncan said.

Tony Parker added 32 points and eight assists for the Spurs.

Phoenix's Steve Nash, who scored 31 points, missed much of the final minute after suffering a bloody cut on the bridge of his nose in a collision with Parker.

He finally went to the bench with about a minute to play and did not return until the closing seconds of the game.

Duncan had the Spurs' go-ahead points, breaking a 102-102 tie with a field goal 1:58 from time.

Parker followed with a jumper 35 seconds later and San Antonio never trailed again.

Parker said his ability to shoot outside played a key role in his game.

"I needed to knock down my outside shots," Parker told reporters.

"It's been like that the last two years, every time I play against Phoenix. They are going to give me that shot. If I am able to make that one, then I can penetrate, find my team mates and get everybody involved."

After Parker's final field goal put San Antonio 106-102 ahead, the Spurs scored their final five points at the line.

"It's about like a heavyweight champ," Phoenix coach Mike D'Antoni told reporters. "You've got to knock them out, and we didn't do that."

Nash went out of the game with 54 seconds remaining and the Suns down by two. He returned with nine seconds left and the Spurs in control at 110-106.

Amare Stoudemire added 20 points, 18 rebounds and five blocked shots for the Suns.

"Physically, I thought he (Stoudemire) played as good as he has played against me," Duncan said. "He challenged every shot."

Game Two is in Phoenix on Tuesday.
