Agassi then recaptured the No. 1 ranking once again on June 16, 2003, which he held for 12 weeks until September 7, 2003. During his career, Agassi held the No. 1 ranking for a total of 101 weeks. Agassis ranking slipped when injuries forced him to withdraw from many events. He did manage to reach the US Open semifinals, where he lost to Juan Carlos Ferrero and surrendered his No. 1 ranking to Ferrero. At the year-end Tennis Masters Cup, Agassi lost in the final to Federer and finished the year ranked No. 4. At age 33, he was the oldest player to rank in the top 5 since Connors, at age 35, was No. 4 in 1987.
