He achieved his highest ATP-ranking on 8 June 1987, when the right-hander was listed as the number 22 player in the world.

Benhabiles's professional career began in 1981, the year he won the junior championship at the French Open, and it ended in 1992.

With his new coach, Brad Gilbert, Roddick won the U.S. Open and was ranked by the ATP as the top player in the world before the end of 2003.

After Roddick, Benhabiles coached Richard Gasquet (until January 2004), Tatiana Golovin (in 2006), Benjamin Becker, and Vania King.

In November 2023, he coached junior grand slam semi-finalist Arthur Gea to his maiden tournament victory as a pro.
