Ukrainian tennis player Marta Kostyuk recently appeared to take a subtle dig at world No. 1 Aryna Sabalenka and No. 2 Iga Swiatek.
In an interview, the world No. 27 hinted that the top players’ “testosterone” levels might be influencing the sport’s rankings.
Sabalenka seemingly clapped back at the claims by sharing a series of racy photos on Instagram.
