Paris - American 13th seed Madison Keys proved too strong for Kazakhstan's Yulia Putintseva on Tuesday as she reached the French Open semi-finals for the first time.
The 23-year-old, who lost to compatriot Sloane Stephens in last year's US Open final, could next face a repeat of that match at Flushing Meadows after a 7-6 (7/5), 6-4 victory over world number 98 Putintseva.
The 10th-seeded Stephens takes on Russian Daria Kasatkina in the second women's quarter-final later on Tuesday.
