'Unknowns' have a history of making a splash

PARIS - If Jelena Ostapenko beats Simona Halep to win the French Open on Saturday, she will become the first tennis player - male or female - in 20 years to earn a first tour-level title at a Grand Slam.

The last to do it? Gustavo Kuerten, who won the men's trophy at Roland Garros on June 8, 1997.

Unseeded, ranked only 47th and never before past the third round at any major tournament, Ostapenko is about as surprising a finalist as there can be on this stage.
