According to SAP Tennis Analytics, five players dominated the clay season in 2017. Led by World No.1 Simona Halep, French Open champion Jelena Ostapenko, Rome champion Elina Svitolina, Kiki Bertens, and Kristina Mladenovic all distanced themselves from the pack on clay. 

Despite a lackluster first three months of the season due to knee injury, Halep found her footing once again on European clay. Playing just four clay events this year, the two-time Roland Garros finalist posted the best winning percentage and earned more points on the clay than anyone else on tour. In the four biggest events of the clay season, Halep strung together run after run, making the semifinal in Stuttgart (l. Siegemund), defending her title in Madrid, making the final in Rome (l. Svitolina), and capping things off with a return to the French Open final (l. Ostapenko). 


1. Simona Halep (ROU): 85.7%
2. Elina Svitolina (UKR): 83.3%
3-T. Kiki Bertens (NED): 80%
3-T. Jelena Ostapenko (LAT): 80%
5. Kristina Mladenovic (FRA): 78.9%
6. Laura Siegemund (GER): 75%
7. Elise Mertens (BEL): 68.4%
8. Anastasija Sevastova (LAT): 68.2%
9-T. Anett Kontaveit (EST): 66.7%
9-T. Caroline Garcia (FRA): 66.7%
9-T. Caroline Wozniacki (DEN): 66.7%
9-T. Samantha Stosur (AUS): 66.7%

Kiki Bertens, Gstaad, Ladies Championship Gstaad

Halep would have swept the stats if not for Bertens' grinding clay season. The 2016 Roland Garros semifinalist captured two more clay titles this season, defending her trophy in Nurnberg and winning Gstaad, while also making her first Premier 5 semifinal in Rome. Playing in eight events, Bertens tallied the most wins on clay in 2017, notching 24 wins.


1. Kiki Bertens (NED): 24-6
2. Simona Halep (ROU): 18-3
3. Jelena Ostapenko (LAT): 16-4
4. Elina Svitolina (UKR): 15-3
5. Kristina Mladenovic (FRA): 15-4
6. Anastasija Sevastova (LAT): 15-7
7. Elise Mertens (BEL): 13-6
8. Carla Suárez Navarro (ESP): 13-7
9. Irina-Camelia Begu (ROU): 13-7
10. Laura Siegemund (GER): 12-4

Kristina Mladenovic, Simona Halep, Madrid, Mutua Madrid Open

Mladenovic's end-of-season rankings surge, which saw her make her Top 10 debut despite her post-Wimbledon struggles, was due in large part to her breakout clay season. The Frenchwoman made back-to-back finals in Stuttgart (l. Siegemund) and Madrid (l. Halep), before defeating defending champion Garbiñe Muguruza en route to her first Roland Garros quarterfinal (l. Bacsinszky). 


1. Simona Halep: 3,070
2. Jelena Ostapenko: 2,430
3. Elina Svitolina: 1,620
4. Kristina Mladenovic: 1,386
5. Kiki Bertens: 1,341
