Roddick and fellow tennis pro Mardy Fish plan to play Wade in H-O-R-S-E. The game is tentatively set for Sunday following Heat practice, although the tennis players' schedules may necessitate a change.

For Wade, victory should be a slam dunk. He's the NBA scoring leader, while Roddick always disparages his basketball abilities.

Roddick and Fish are in South Florida for the Sony Ericsson Open.

"Mardy's actually got a pretty good shot," fellow tennis pro James Blake said. "Hopefully the cameras will be rolling and you can watch Andy throw up a few bricks. ... If they're both together and they get about five extra letters, they might - no, they still don't have a chance."
