Yastremska D. vs Chwalinska M.

Published reasoning

Estimated probability: 73%. Chwalinska took sets in six of nine comparable hard-court matches, including September wins over Mertens, Oliynykova and Sramkova and a three-set loss to Fernandez. She is ranked 21 versus Yastremska's 111. Comparable counts use supplied completed hard best-of-three results from 19 July to 2 October, excluding incomplete scores. Main risk: Yastremska just beat McNally 2-0 and took sets in three of her four comparable matches. Chwalinska lost 0-2 to Townsend, Shnaider and Gibson; the opponent's current sample is small and there is no H2H.
