The Australian tennis player Lleyton Hewitt has continued his career revival by reaching the fourth round of the U.S. Open in New York.
32-year-old Hewitt, the champion at Flushing Meadows in 2001, recovered from a lapse in the second set to defeat Russia's Evgeny Donskoy in four.
Hewitt will face either Germany's 12th seed Tommy Haas or 21st-seeded Russian Mikhail Youzhny for a berth in his first quarter-final at a major since Wimbledon in 2009.
