Federer & Nadal to meet in final
Sunday’s final will be Federer’s 15th meeting with Nadal (right)
The world number one was leading 6-3 3-2 before the Serbian retired after complaining of feeling dizzy.
Nadal, the three-times defending champion, had earlier beaten Nikolay Davydenko 6-0 6-2.
The Spaniard was rarely troubled and will meet Federer in Sunday’s final for the third consecutive year.
