The Suns grabbed the rebound and got the ball in the hands of Marbury, who raced up court. With the clock running down, he pulled up for a runner from just outside the 3-point line at the top of the key that caromed off the backboard.
The officials counted the basket after briefly reviewing replays. There was no argument from the Spurs.
"That shot was a teardrop from God," Marbury said. "Things were getting tough, but I didn't stop shooting. We never gave up, we never got ourselves into a situation where we'd panic."
