To my knowledge these are all the players that need to be added to the list. i.e. players born 1987 onwards that have broken Top 100 but not Top 50.
1987: Soler-Espinosa, Malek, Kudryavtseva, Savchuk, Zec Peskiric
1989: Panova, Tsurenko, Duque Marino, Zhang, Rodina, Dolonc, Olaru, Kulikova
1990: U.Radwanska, Rus, Hampton, Falconi, Cadantu, Tatishvili, Voegele, Pivovarova
1991: Bertens, Giorgi, Chang, Vandeweghe
1993: Babos, Stephens, Larcher de Brito
Am I missing anyone?
Stephens will be Top 50 after Wimbledon anyway, and Giorgi will be Top 100.
