MADRID, Spain -- Andy Roddick will try to claim the No. 1 ranking in tennis in the home country of top-ranked Juan Carlos Ferrero.

"I'm ready for No. 1," Roddick said.

The U.S. Open champion leads the calendar-year ATP Champions Race entering Tennis Masters Madrid, which starts Monday. By the end of the week, he also could be first in the ATP Entry Rankings.

Ferrero has led the 52-week rankings the past five weeks. Roddick is second.

Wimbledon champion Roger Federer, seeded third in Madrid behind Ferrero and Roddick, is also looking to be No. 1. Federer beat Carlos Moya in Vienna, Austria, on Sunday for his sixth title of the year.

"I am not far away, and I will hang on and see what happens," he said.

Last year, Madrid replaced Stuttgart in the Tennis Masters Series, the most prestigious tournaments behind the four Grand Slams. This is the next-to-last stop in the nine-tournament series, which ends in Paris.
