American legend Andre Agassi ensured that 21-year-old countryman Andy Roddick would claim the year-end No. 1 World ranking when he defeated Juan Carlos Ferrero 2-6, 6-3, 6-4 at Tennis Masters Cup Houston on Wednesday night. Agassi’s win means that Ferrero cannot reach the semifinals and cannot pass Roddick in the ATP Champions Race. Roddick becomes the youngest American in history to end the season No. 1.

Andy Roddick on finishing year No 1:

“I’m incredibly honored to finish the year as No. 1, but I’m probably more proud to be the sixth American ever.  It’s hard to reflect on what a year this has been, but I’m incredibly fortunate to be playing at home in the United States.  To be able to share all of this with my friends and family is better than I could have ever imagined. “
