May 2017 WTA Breakthrough Performance of the Month Finalists:

Ons Jabeur: A lucky loser at the French Open, Jabeur lit up the City of Lights to become the first Arab women to reach the third round at a Grand Slam. Junior champion back in 2011, she stunned reigning BNP Paribas WTA Finals Singapore presented by SC Global champion Dominika Cibulkova in straight sets for her best-ever major result that put her within striking distance of a Top 100 debut.

Jelena Ostapenko: The Latvian enjoyed a major breakthrough of epic proportions at the French Open, taking home the title over No.3 seed Simona Halep in a three-set final. Never before past the third round at a major tournament, Ostapenko stunned Samantha Stosur, Caroline Wozniacki, and Timea Bacsinszky - all in three sets - and used her awesome power game to roar back from a set and a break down against the Romanian to rocket into the Top 20 for the first time in her young career.

Veronica Cepede Royg: The Paraguayan star was behind one of the French Open's first big surprises when she survived a three-setter against pre-tournament darkhorse Anastasia Pavlyuchenkova en route to the fourth round. Once there, she gave eventual semifinalist Karolina Pliskova all she could handle in a three-set thriller.

Caroline Garcia: Garcia flew above her previous best results at the Grand Slams to reach her first career quarterfinals, navigating a tense three-setter against Hsieh Su-Wei before putting on a decisive performance to defeat fellow Frenchwoman Alizé Cornet. Playing Pliskova tough through three sets, Garcia finished within one spot of a Top 20 debut at No.21.
