Belgian Justine Henin-Hardenne overtook compatriot Kim Clijsters as the women's world number one when she beat Yugoslav Jelena Dokic 6-0 6-4 in the final of the Swisscom Challenge today.
Henin-Hardenne was in a class of her own against world number 25 Dokic, winning her eighth tournament in 17 this year.
The US and French Open champion missed out on the number one spot last weekend when she lost to Clijsters in the Filderstadt Grand Prix but made no mistake today.
"It is just an amazing feeling," she said. "Now I am number one in the world it is just amazing because I did everything I could and it is a real achievement."
