Houston ? NBA basketball is a big man’s game.

Don’t tell that to 5-foot-9 Nate Robinson.

The New York Knicks’ rookie won the NBA All-Star slam-dunk competition Saturday night, beating out 6-foot-6 Andre Iguodala of Philadelphia, 6-9 Hakim Warrick of Memphis and 6-9 defending champ Josh Smith of Atlanta.

Robinson, who earned a $35,000 first prize, electrified the Toyota Center by taking a bounce pass from Spud Webb, the 1986 champion, and leaping over the 5-7 Webb to jam. The stunt earned a perfect 50-point score to force a dunk-off against Iguodala, who had received two perfect scores.

In the dunk-off, Robinson jammed on the 14th try, catching his own pass off the backboard. He earned 47 points, edging Iguodala by a point.

Each player dunked twice in the first round, with a panel of five judges awarding composite scores between 30 and 50 points. The top two scores advanced to the finals.
