Meet the Penickova sisters

Kristina and Annika Penickova of the United States are the latest sisters to be making their way in tennis and have been progressing impressively along the player pathway.

They were crowned Australian Open girls' doubles champions in January, while both have had progressive seasons. Kristina is currently the No. 1-ranked girl on the planet and finished runner-up at October's ITF World Tennis Tour Junior Finals. 

Kristina and Annika are currently competing at the 2025 Billie Jean King Cup by Gainbridge Junior Finals in Santiago, Chile alongside teammate Julieta Pareja and under the stewardship of captain Georgi Rumenov.

The United States are bidding for a record-extending 10th Billie Jean King Cup Juniors title and their fourth in succession. All of their matches, together with all those at both the 2025 Billie Jean King Cup and Davis Cup Junior Finals, can be re-watched on the ITF's junior tennis livestreaming platform.
