Romanian tennis player known for his on-court histrionics and outstanding Davis Cup play. He was the first European to surpass $1 million in career prize money and was ranked number one in the world in 1973.

A Davis Cup player since 1966, Nastase almost single-handedly powered Romania to the finals in 1969, 1971, and 1972, although the United States won each time. The most heartbreaking loss for Nastase occurred in 1972, when the United States retained the Davis Cup after Stan Smith defeated Nastase in the singles. After winning the U.S. indoors and Italian singles in 1970, Nastase won the Grand Prix Masters in 1971–73 and 1975 and the U.S. Open against Arthur Ashe in 1972. In 1973 he won the Italian and French singles titles and combined with Jimmy Connors for the U.S. Open doubles in 1975.

Nastase consistently was ranked much higher in world ratings than his major tournament record would seem to indicate, placing him among the top 10 players from 1970 to 1977. His outstanding professional indoor record made him a perennial contender, but his on-court antics and temper tantrums caused a record of disqualifications, fines, and suspensions. At his best, Nastase was a fast player and exhibited intricate footwork and brilliant ball handling in lobbing past opponents.
