Aryna Sabalenka is skipping the first leg of the North American hard court swing after a taxing European summer.

Sabalenka, the top seed at the Wimbledon Championships, was upset by No. 13 Amanda Anisimova in three sets on Thursday, and in the midst of their battle, Sabalenka apparently didn't love something the American pulled. In the second set, Anisimova, of the United States, celebrated a point before the ball went by Sabalenka.

Aryna Sabalenka had a moment of poor sportsmanship during her loss to American Amanda Anisimova in the semifinals at Wimbledon on Thursday.
