Sofia Costoulas Player Overview
Sofia Costoulas has been in impressive form, securing four consecutive victories in Auckland, including qualifying rounds. In her latest match, she dominated Caitlin Quevedo (6-2, 6-0), although she has yet to face a top-100 opponent in the main draw.

However, the Belgian excels on break points, winning an impressive 50% of them.

⭐ Editorial Prediction
The upcoming match promises to be engaging and fiercely contested, despite the gulf in rankings between the opponents. Both athletes display confident play, focusing on a strong first serve and high efficiency in converting break points. While the favorite is clear due to the difference in class, we want to highlight some less obvious factors. Jovic, despite securing two wins in Auckland, conceded 17 games, dropped a set, and even played a tiebreak. The Belgian consistently wins over 9.5 games across seven consecutive matches and hasn't lost by more than four games over that stretch. We suggest backing the underdog and taking Kostulas with a +4.5 handicap.
