PARIS—Bent over with her hands covering her face, her knees getting dirtied on the red clay court, Mirra Andreeva was celebrating—processing might be the more appropriate word—how she had finally overcome “so many demons inside” that came with being a teenage tennis phenom.
After bursting onto the scene at 15, Andreeva became a Grand Slam champion at 19 when the Russian ended the run of 114th-ranked Polish qualifier Maja Chwalinska with a 6–3, 6–2 victory in the French Open final on Saturday.
