H2H efficiency decisively points UNDER. Ostapenko's 2023 Rome clay victory over Zheng ended 6-4, 6-2 (18 games), well below the 21.5 line. Ostapenko's high-variance game on clay often produces lopsided set scores, leading to rapid finishes. The market's expectation of extended game counts significantly overestimates their recent clay court output. This is a clear Under play. 95% NO — invalid if any single set reaches 7-6.
