Top 10 greatest American tennis players of all time

#6 Andre Agassi

Andre Agassi and Steffi Graf

Andre Agassi is a former World No. 1, who was one of the game's most dominant players from the early 1990s to the mid-2000s.

Agassi was regarded by both experts and fellow players to have the best service return in the history of the game. Described by the BBC upon his retirement as "perhaps the biggest worldwide star in the sport's history", Agassi exhibited performances that were par excellence.

With his unorthodox style of clothing and attitude, Agassi is one of the most charismatic players in tennis ever.

He is the only man in tennis to achieve the 'Career Super Slam' as described by Sports Illustrated Magazine. That involves winning all 4 Grand Slams, the Olympics Gold and the ATP Finals.

Agassi won 8 Grand Slams including 4 Australian Open titles. His last Grand Slam came at the 2003 Australian Open.

Agassi is married to another tennis legend Steffi Graf, and the two of them combined have 30 Grand Slam Singles titles.
