Juan Martin del Potro has now been the youngest slam winner for well over three years, and this looks set to continue for a while. He is now one of the players to have this distinction for the longest. How much longer will he remain the youngest slam winner? Borg looks within reach, could he even beat Chang?
Here is an overview of slam winners that have been youngest for three years or more (Open Era only):
Michael Chang: FO 1989 to FO 1996 - 7 years
Björn Borg: FO 1974 to USO 1979 - 5 years 4 months
Boris Becker: W 1985 to RG 1989 - 3 years 11 mounts
Juan Martin del Potro: USO 2009 to ? - 3 years 8 months (to FO 2013) and counting
Gustavo Kuerten: FO 1997 to USO 2000 - 3 years 4 months
Mats Wilander: FO 1982 to W 1985 - 3 years 1 month
I've just understood what you meant, it was quite hard actually
you mean at one moment in time, the youngest guy to have already won a slam before,
and that this streak would be stopped when somebody born from 1989 or after the 23rd of september 1988, wins a slam.
Borg's streak would be defeated if nobody born from 1989 wins a slam in 2013 or 2014.
Honestly it has a big chance to happen.
Chang's streak will be tougher to get ahead of.
But anyway, in another definition, Chang is still the youngest guy to have ever won a slam, in a meaning that nobody did it at a younger age than him.
