Jose Higueras was born on an olive plantation in Granada, Spain, some 58 years ago. Later, he was a ball boy at a tennis club in Barcelona.
He was a patient professional, most comfortable on the soft clay; 17 of his 18 titles came on the dirt. He was a semifinalist at Roland Garros in 1982 and 1983. He was much sought after as a coach and helped a number of players win the title he never could in Paris. Today, he works for the USTA as the director of coaching for elite player development. His mind remains as agile as his game used to be.
"All sports -- except maybe chess -- are sports of movement," said Higueras from his home in Palm Springs, Calif. "In tennis, it is absolutely vital."
Clearly, he has given this a great deal of thought. In a recent 30-minute conversation, he offered a nuanced catalogue of the world's best movers, past and present. He and a dozen other respected experts ranked the best movers on clay, on hard courts, men and women, now and then. Here are those collective (and highly subjective) results:
