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

Anisimova, 23, will return to Centre Court for Saturday's final against No. 8 Iga Światek, who steamrolled Belinda Bencic, 6-2, 6-0. 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.
