Aryna Sabalenka secured her second consecutive Brisbane International title by defeating Marta Kostyuk in straight sets. The final match was marked by heightened tension, partly due to prior comments made by Kostyuk regarding Sabalenka's testosterone levels. Despite Kostyuk's aggressive play and flashes of brilliance, Sabalenka maintained control, capitalizing on errors and securing the win in just over an hour. Sabalenka's victory serves as a confidence boost ahead of the Australian Open.
