Wednesday, the Supreme Court is to hear Martin's case against the PGA Tour for the right to ride a cart.
Martin has Klippel-Trenaunay-Weber syndrome in his right leg, a degenerative disease which makes it difficult for him to walk 18 holes. He successfully sued the PGA Tour three years ago for the right to use a cart. A federal appeals court in San Francisco upheld the decision.
Martin qualified for the PGA Tour in 2000, but failed to keep his card. He is playing in this week's Tucson Open on one of his seven sponsor's exemptions.
