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.

The world’s top female tennis player was embroiled in a heated moment in Thursday’s semifinals match at Wimbledon.

The American No. 13 seed did not shrink from her duel with Sabalenka on Centre Court, going after her shots at all times.
