Sofia Costoulas holds a substantial edge in this ITF W35 Vigo hard-court first-round match as the higher-ranked Belgian with a career-high singles mark of 134 and consistent results across ITF and WTA 125 events in 2026. Her recent form includes strong showings on similar surfaces, while Spanish opponent Eva Alvarez Sande sits outside the top 1300 with far fewer professional wins and limited exposure at this level. Surface familiarity, ranking differential, and head-to-head experience favor Costoulas, though Alvarez Sande could benefit from home-country support and any early-match adjustments on the outdoor courts. No major injury concerns or withdrawals have been reported for either player ahead of the scheduled start.
