Jelena Ostapenko is now working with experienced WTA coach David Taylor, the Latvian told local press this week.
Ostapenko had been working with Anabel Medina Garrigues, who stopped coaching the 20-year-old because she was appointed Spanish Fed Cup captain.
The two began working together during the clay-court season, and Medina Garrigues helped Ostapenko to a surprise win at the French Open.
"I've been practicing with David Taylor for two weeks," Ostapenko told Latvian press.
