Aryna Sabalenka says she has written to Coco Gauff to apologize for the “unprofessional” comments she made following her loss to her American rival in the final of the French Open.

Coco Gauff became the first American to win the French Open women's title since Serena Williams after beating top-ranked Aryna Sabalenka in three sets on Saturday. It is her first French Open title and her second major overall.
