* Michel Sutter, Vainqueurs Winners 1946–2003, Paris, 2003. Sutter has attempted to list all tournaments meeting his criteria for selection beginning with 1946 and ending in the fall of 1991. For each tournament, he has indicated the city, the date of the final, the winner, the runner-up, and the score of the final. A tournament is included in his list if: (1) the draw for the tournament included at least eight players (with a few exceptions, such as the Pepsi Grand Slam tournaments in the second half of the 1970s); and (2) the level of the tournaments was at least equal to the present day challenger tournaments. Later, Sutter issued a second edition of his book, with only the players, their wins, and years from 1946 to 27 April 2003, period.

## Other titles (24)

Here are Năstase's tournament wins that are not included in the statistics on the Association of Tennis Professionals (ATP) website. The website is incomplete from 1968 to 1970 and has some omissions for tournaments held since 1968.
Năstase won several tournaments during the early years of his career that were equivalent to the present day "challenger" tournaments. Because the term "challenger" started to be applied to second-rank tournaments in 1978, those tournaments are termed "minor tournaments" in the following list.
* 1967 – Cannes (minor tournament), Travemünde (minor tournament)
* 1968 – Viareggio, Bucharest (minor tournament)
* 1969 – Madras (minor tournament), New Delhi (minor tournament), Gauhati (minor tournament), Travemünde, La Corogne, Budapest, Denver
* 1970 – Napoli, Ancona
* 1971 – Istanbul
* 1973 – Istanbul
* 1974 – Portland
* 1975 – Helsinki, Dutch Round Robin (Utrecht Netherlands), Graz, Uppsala
* 1976 – Caracas (a four-man invitation tournament in October, not to be confused with the Caracas WCT in March that was won by Raúl Ramírez), Argentine Round Robin (invitational tournament)
* 1977 – Rotterdam World Star (invitational tournament)
* 1978 – Frankfurt (invitational tournament)
