Canada’s Daniel Nestor and Serbia’s Nenad Zimonjic beat American twins Bob and Mike Bryan 7-6 (3), 6-2 on Sunday in the Masters Cup doubles final to clinch the year-end No. 1 ranking.
The Bryans, seeking their third straight title in the event, had held the top ranking and won the Olympic bronze medal in August.
But Nestor and Zimonjic have beaten the Americans three straight times and went through the tournament undefeated, taking all three of their round-robin matches and the semifinals. Zimonjic also won the mixed doubles in the Australian Open with Tiantian Sun.
