For all his brilliance, Bjorn Borg never won the Australian or U.S. Opens. Jimmy Connors joins the list of those left frustrated in Paris.

Winning individual Grand Slam titles is nice, but winning all four is an even higher measure of greatness. That’s probably why only 14 players — five men and nine women — can claim at least one victory in each of tennis’ four major events.

Here’s the list, with the year the player completed that “career slam.”:

MEN

– Andre Agassi, USA (1999)

– Don Budge, USA (1938)

– Roy Emerson, Australia (1964)

– Rod Laver, Australia (1962)

– Fred Perry, Great Britain (1935)

WOMEN

– Maureen Connolly, USA (1953)

– Margaret Court, Australia (1963)

– Chris Evert, USA (1982)

– Steffi Graf, Germany (1988)

– Doris Hart, USA (1954)

– Shirley Fry Irvin, USA (1957)

– Billie Jean King, USA (1972)

– Martina Navratilova, Czechoslovakia/USA (1983)

– Serena Williams, USA (2003)
