Sofia Costoulas vs Tereza Mrdeza Prediction
Sofia Costoulas faces Tereza Mrdeza in a Roland Garros qualifying match, with Costoulas holding a significant advantage in current ranking and recent match play against an extremely inactive Mrdeza.
Sofia Costoulas host Tereza Mrdeza at Paris, France on Monday, part of the 2026 WTA - Roland Garros season. ATP/WTA rankings, surface form, and head-to-head record are factored into the model alongside the prediction below.
ATS PREDICTION
Sofia Costoulas Win
Predicted: 2-0
⚡68%
Sofia Costoulas, ranked 146, enters this match with a significant advantage in recent match play and current form, holding a 19-12 record in 2026. Her opponent, Tereza Mrdeza, is currently unranked and has played only one match in 2026, indicating extreme inactivity and a severe lack of match fitness. While Costoulas retired from her last match, her overall rhythm and clay court experience (53-47 career) are far superior to Mrdeza's outdated clay record. Given Mrdeza's prolonged absence from professional tennis, Costoulas is expected to dominate this first-round qualifying match at Roland Garros.
SPREAD PREDICTION
Costoulas -5.5 games (-5.5)
82%
Tereza Mrdeza's extensive period of inactivity and lack of match fitness will likely result in numerous unforced errors and struggles on her serve. Sofia Costoulas, despite her recent retirement, has a solid clay court game and sufficient match rhythm to capitalize on Mrdeza's rustiness. This disparity in current form and fitness suggests Costoulas will win comfortably, covering a -5.5 game spread with relative ease through multiple service breaks.
TOTAL PREDICTION
Under 19.5
78%
Considering Tereza Mrdeza's severe lack of match play, it is highly probable that she will struggle to be competitive in many games, leading to short sets. Sofia Costoulas, even with a potential minor fitness concern from her recent retirement, possesses the current form and ranking to secure a quick victory. A 2-0 win for Costoulas with scores like 6-3, 6-2 or 6-2, 6-3 would comfortably keep the total games under 19.5, as Mrdeza's rustiness will limit her ability to extend rallies or hold serve consistently.
