Steffi Graf Movement on Clay: Steffi grew up playing on clay. So, perhaps, it is no surprise that she can slide on the stuff. Still, it is more evidence of her superior movement. It is also one of the primary reasons why she has such an unmatched record on all surfaces. She not only had the speed to compete on grass and hardcourts, but she had the balance and agility to complete on clay. French 1999
