Predictions for Elise Mertens — Barbora Krejcikova

Elise Mertens meets Barbora Krejcikova in the second round of WTA Singapore on September 23 at 06:00 UTC. The defending champion arrives without a match on these courts, but also without three hours of Tuesday tennis in her legs.

Mertens brings rhythm; Krejcikova brings mileage

Mertens’ US Open ended with a narrow 3-6 6-3 5-7 defeat to Naomi Osaka, a match in which she grew more assertive and erased three match points. That followed a Monterrey final, so her recent hard-court level has been both substantial and well tested.

Krejcikova snapped a three-match losing run by beating world No. 266 Anna-Lena Friedsam 6-0 5-7 7-6, but the escape took almost three hours. She faced match points, failed to serve out the contest and reportedly required treatment for lower-back discomfort, although the seriousness remains unclear.

Freshness should simplify a complicated matchup

Krejcikova’s changes of pace, slices and willingness to move forward can make baseline rhythm disappear rather quickly. Yet sustaining that variety is harder on a short turnaround, especially when Mertens can keep returning deep and ask for one more full-blooded swing.

Their January hard-court meeting offers Mertens a useful map: she recovered from a set down and won after stepping closer to the baseline and taking greater risks. A slow start after the bye is the obvious danger, but her stronger recent form, fresher legs and proven adjustment in this matchup make her the clear choice.
