Aryna Sabalenka vs Marta Kostyuk Predictions & Picks
Our Pick: Marta Kostyuk +3.5 Games @ +125
Sabalenka has not dropped a single set across four encounters against Kostyuk so far. However, the Ukrainian No. 2 has looked in fine form this week. She is striking the ball more fearlessly than ever before, beating three Top-10 players in the process. Moreover, the youngster has a score to settle with the tigress after years of being unable to defeat her. While we still predict a Sabalenka victory on the night, Kostyuk +3.5 games at a price of +125 seems to be an appropriate bet.
This is set to be Sabalenka’s third straight appearance in the Brisbane International final. The 27-year-old finished as the runner-up at the WTA Finals in Riyadh, and returned to Australian soil where she will compete for a third crown at Melbourne Park in four years. While she converted only 25% break point opportunities generated against Muchova, the Belarusian didn’t allow her opponent to break her serve even once.
Kostyuk likes to take the attack to baseline dominators, and spreads the play to open up the court. Against Pegula, the 16th seed picked up yet another victory over a higher ranked player. Needing under an hour to dismantle the American 6-0 6-3, Kostyuk is set to enter the final with a lot of energy left in the tank.
