The Kazakh ends the year on an 11-match winning streak, and back in the Top 5 of the WTA rankings.

The two undefeated group winners and long-time rivals square off for the championship.

She'll face Elena Ryabkina in the championship match, as both women vie for their first year-end crown and a record payout.

Rybakina extended her unbeaten season-ending run to 10 straight victories with a 4-6, 6-4, 6-3 comeback.

Fierce ball-striking and a US Open final rematch highlight the semifinals in Riyadh.

How Anisimova used her worst defeat as inspiration for her biggest wins yet.

The world No. 1 turned a 5-3 first-set deficit into a 7-6(5), 6-2 win to advance to a semifinal match with Amanda Anisimova. Pegula will play Elena Rybakina in the other.

Both semifinal spots remain up for grabs in the Stefanie Graf Group; can No. 1 Sabalenka avenge a Roland Garros loss to Gauff?

Anisimova handed Swiatek a second straight loss from a set ahead to take the semifinal spot, 6-7(3), 6-4, 6-2.

A Wimbledon final rematch will determine the second semifinalist from the Serena Williams Group.

She also walked away knowing that, even against the WTA’s best, her power alone can be enough.
