World number ones Andy Roddick and Justine Henin-Hardenne have been named 2003 ITF world champions.
American Roddick (21) earned the award after winning his first grand slam crown at the US Open in September as well as reaching the semi-finals at the Australian Open and Wimbledon.
Belgian Henin-Hardenne, also 21, was twice a grand slam winner in 2003, beating her compatriot Kim Clijsters to clinch both the French and US Open titles.
