Winston-Salem, NC (SportsNetwork.com) - Second seed Kevin Anderson posted a second-round victory, while former top-10 star Tommy Robredo went by way of an upset Tuesday at the Winston-Salem Open, a final U.S. Open tune-up.
The 6-foot-8 South African Anderson, who played collegiate tennis at the University of Illinois, held off Frenchman Adrian Mannarino 6-3, 2-6, 6-4 on the hardcourts at Wake Forest University.
Upsets came when France's Nicolas Mahut vanquished the third-seeded Spaniard Robredo 6-1, 7-6 (7-0), hot Belgian qualifier David Goffin doused fourth- seeded Argentine Leonardo Mayer 6-3, 6-1, and 6-foot-8 Pole Jerzy Janowicz dismissed sixth-seeded Portuguese Joao Sousa 6-1, 3-6, 7-6 (7-5). Goffin has actually won his last 24 matches, including an ATP title in Kitzbuehel and three straight Challenger Tour championships.
