7 teenagers to have won a Grand Slam title in the Open Era

#1 Michael Chang: 17 years 109 days (1989 French Open)

Michael Chang became the youngest Open Era Grand Slam champion at the 1989 French Open

Making his fifth Grand Slam appearance at the 1989 French Open, Michael Chang dropped a set in his opening round against Eduardo Masso. Respective straight-sets wins over future World No. 1 Pete Sampras and Spanish qualifier Francisco Roig then propelled the American to the second week of the tournament.

The inspired run of the 17-year-old seemed set to end when Chang fell behind two sets against top-seed and three-time champion Ivan Lendl. But Chang was made of sterner stuff.

The teenager reeled off the next three sets for the loss of three games apiece to upset the world's top-ranked player, before dropping a set against Ronald Agenor in the quarterfinals.

In the last-four, Chang conquered defending champion Mats Wilander's conqueror Andrei Chesnokov in four sets to set up a title clash with third seed Stefan Edberg. Chang took the opener against the Swede in the final before falling behind two sets to one.

A set away from winning the French Open, Edberg faltered as a tiring Chang threw down an underarm serve. The American eventually triumphed in five sets to become the youngest winner of a Grand Slam title in the Open Era.
