Martin back at US Open

American Casey Martin, who made history in 1998 by being allowed to use a golf cart to play in the US Open, will be back at the Olympic Club in San Francisco next week after winning a qualifying event.

The 40-year-old suffers from Klippel Trenaunay Weber syndrome, a birth defect in his right leg, and successfully sued the PGA Tour in 2001 for the right to use a cart during competition.
