The Monterrey final pairs Elise Mertens, a ten-time tour champion and a heavy favourite at 1.47, with Diane Parry, who is playing for the first title of her career at 2.68. The two met on the same surface two weeks ago in Cincinnati, and Parry won. The market has largely filed that result away.
One week of work, two very different weeks
Parry got here through Vekic, Oliynykova, Tauson and Li, and in each of those matches she had to level the score from a losing position. Her pattern is unchanged: a deep slice that sits at an awkward height, then a forehand accelerated down the line. That was exactly the sequence that pulled Mertens out of her rhythm in Cincinnati after the Belgian had taken the opening set.
Mertens has been more fragmented. Against Osaka in Toronto she was pushed behind the baseline and stayed there, and both her opening match and her semifinal in Monterrey were won through her opponent's nerves rather than her own best tennis. The experience of finals is real and may decide the closing games; the level underneath it has not been assembled for a full match yet.
Why three and a half games is the right number
Parry has not lost a set heavily all week, and her return of second serve guarantees break chances here. Mertens produces one-sided scorelines against passive opponents, which Parry is not.
The handicap covers an outright French win and the tight loss that a debut final might produce.
Prediction: Parry +3.5 games, odds 1.85
