Starodubtseva meets Mertens in the Monterrey quarterfinals on Thursday evening, and the market sees a wide gap: 1.50 against 2.59. That price leans on ranking, titles and the Wimbledon run in which Mertens beat Rybakina.
The schedule points elsewhere. Mertens needed three sets on Wednesday and returns for a night match, while Starodubtseva had a full day of rest.
Two very different hard-court months
Mertens' summer on hard courts has alternated bright passages with abrupt drops. In Cincinnati she took the opening set against Parry and lost the next two; in Monterrey she won six games in a row against Udvardy, then went 0-4 in the second set. The double faults arrive in clusters: six that day, eleven against Bondar.
Starodubtseva came here off a long winless stretch and has looked composed for the first time in months. She beat the seeded Tien and then Tagger, both in straight sets, 19 games in each match. In Memphis and Toronto she kept giving back won opening sets, which is exactly what has stopped in Mexico.
Why the underdog price is too long
Mertens is the better and more varied player, and on a clean serving day she can take a set for almost nothing. The risk is real. But nearly every recent hard-court match of hers contains a stretch where four or five games disappear in sequence, and Starodubtseva is currently closing sets rather than losing them.
They have never met, so the tactical solving has to happen live, on tired legs, in an evening quarterfinal. At 2.59 the value sits with the Ukrainian.
Prediction: Starodubtseva to win, odds 2.59
