Now along comes Jack Sock, a 22-year-old born in Nebraska and a Florida resident, who calls the slow stuff "my favorite surface."
Yes, that's right, even though there are not many red clay courts in the U.S. — Sock first encountered them in Europe — and even though, at first glance, they're considered less than ideal for players who thrive on speedy serves and forehands. Sock and another U.S. man, 16th-seeded
"This just suits my game very well," Sock said. "I'm able to take my time and kind of maneuver the ball around. Movement is another big part of my game. I feel like on the clay, I get to a lot of balls."
