Mochizuki S. vs Watanuki Y.

Published reasoning

Estimated probability: 70%. Watanuki won all 4 completed hard-court matches in the last 30 days in straight sets, including Cilic (rank 80) and Ilagan (194). Mochizuki conceded a set in 5/8, with sweeps by Safiullin, Faria and Damm. Main risk: four matches from one tournament run are a modest sample and two wins came against ranks 432 and 1521; Mochizuki has the much better ranking and just swept Sweeny and Diaz Acosta. The low-quality model is close and there is no H2H, so the estimate is reduced to a cautious set call.
