World No 1 Aryna Sabalenka laid down an Australian Open marker as she brushed aside Marta Kostyuk in the Brisbane International final before making a pointed gesture towards her opponent in the post-match celebrations.
Sabalenka was too strong for Kostyuk, retaining her title in Brisbane with a 6-4 6-3 triumph in just 1hr 17mins before looking down the court at her opponent and kissing both biceps – a likely nod to previous comments made by the Ukrainian that Sabalenka possesses higher testosterone levels than other female players.
