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.

Anisimova, 23, returns to Centre Court for Saturday's final against the winner of Iga Swiatek and Belinda Bencic. Anisimova is trying to become the first American to win a Grand Slam in London since Serena Williams' seventh and final Wimbledon title in 2016.

The USA’s Amanda Anisimova toppled Wimbledon favourite Aryna Sabalenka in a fascinating semi-final, full of red-blooded power hitting and territorial shrieks.
