Aaron Krickstein set an Association of Tennis Professionals (ATP) record as the youngest player to win a singles title when he won a Tel Aviv tournament in 1983 at age 16. A year later, he set another record when he became the youngest player to break into the ATP's top-10 world singles rankings. Both records still stand as of 2023.

Krickstein reached a career-high ranking of number 6 in the world in 1990. He won nine ATP tournaments, defeating many of the top players of his era, including Ivan Lendl, Pete Sampras and Boris Becker. Krickstein was a member of the U.S. Davis Cup team in 1985, 1986, 1987 and 1990.
