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

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.

To some tennis fans, world No. 1 Aryna Sabalenka is the queen of petty. That reputation may have been upheld during Saturday's Wimbledon women's final in which Iga Swiatek dominated Amanda Anisimova in straight sets (6-0, 6-0) to win her first Wimbledon title.
