Botic van de Zandschulp enters the Winston-Salem Open round of 32 as the 13th seed and slight favorite, holding a narrow ranking edge at No. 59 over Adolfo Daniel Vallejo at No. 70. Their only prior meeting came last month in Bastad, where Vallejo prevailed in three sets after dropping the opener. Vallejo has shown strong recent momentum, reaching his first ATP semifinal on clay and securing hard-court wins over players such as Valentin Vacherot while pushing Tommy Paul in Cincinnati. Van de Zandschulp arrives defending points from a runner-up finish here last year but carries a mixed 2026 hard-court record. Surface transition and Vallejo’s rising confidence on outdoor hard courts remain the key variables shaping trader views of the implied probabilities.
