Prognosen für Cori Gauff — Elise Mertens

The first set matters here. Gauff let a big lead slip against Osorio and was serving to stay in the set against Sun; shaky serving and forehand doubts have made her openings less dependable than her finishes.

That makes Over 19.5 games the better price at 1.82. Mertens has started both Beijing matches sharply, then had to recover her grip; against Ostapenko she came back from an early deficit in the decider. Her blocking return can also make Gauff work through service games when the serve wavers.

Gauff has won all five meetings, but three went the distance, including Dubai, where Mertens held match points in a second-set tie-break. She has pushed Gauff before; a one-sided win is not the only plausible shape of this match. Gauff’s outright price is too short given the unsettled starts, while Mertens +4.5 is narrower: a tight straight-sets Gauff win could beat that handicap and still clear the total.

The risk is a sharper start from Gauff, as she produced after the first set against Sun, or Mertens feeling the load of long singles matches and doubles. The abuse Gauff received after the Sun match adds another pressure, though its effect is unknown.
