The Wimbledon semifinal between top-ranked Sabalenka and American Anisimova might not be as straightforward as it seems. We break it down.

Aryna Sabalenka was dragged into a bygone era on Tuesday and tormented for almost three hours on Wimbledon’s Centre Court before finally imposing her 21st-century power game to beat mesmeric Laura Siegemund for a place in the semi-finals.

The world No. 1 was thrown off by Siegemund's changes in pace and rhythm, but came through in three tight, tense sets.
