Madison Keys has withdrawn from a French Open warmup tournament due to a left thigh injury. The 19th-ranked American was set to play at the Internationaux de Strasbourg this week, where she won the title in 2024. Keys says Monday she has decided to withdraw to focus on getting healthy for Roland Garros. The French Open starts on May 24 in Paris. Keys reached the semifinals at the clay-court Grand Slam in 2018. She retired from the final of the Trophee Clarins while leading Diane Parry 6-3, 3-3 on Sunday.
