Last year, Gauff pulled off some heroics to edge out Zheng Qinwen 3-6 6-4 7-6 (2) and win the WTA Finals' inaugural edition in Riyadh. If the American tennis star repeats as the champion at the prestigious season-ending tournament, she will become the first player to do so since her idol Williams.

This year’s WTA Finals doubles field blends continuity and change, with three returning teams, four new pairings built from familiar names and a breakout duo making history as the youngest qualifiers in 25 years.

Anisimova, now ranked a career-high No. 4, will be making her debut at the event after reaching her first major final at Wimbledon, and then following it up with a final appearance at the US Open, in addition to winning 1000-level titles at the Qatar Open and the China Open.
