Zvonareva reaches first US semi-final
Zvonareva, the seventh seed, coped better with the blustery conditions at Flushing Meadows to win a scrappy contest 6-3 7-5 on Arthur Ashe Stadium.
The 26-year-old will face either top seed Caroline Wozniacki or the unseeded Dominika Cibulkova in the last four as she attempts to reach her second successive Grand Slam final, having lost to Serena Williams in the Wimbledon final earlier this year.
