Qualifier Sergio Callejon Hernando enters the Menorca ATP Challenger second round on outdoor clay with strong momentum after upsetting No. 4 seed Zdenek Kolar 5-7, 7-6(5), 6-1 on Thursday, capping his qualifying run that included a 6-3, 6-1 demolition of Denis Yevseyev. Czech Andrew Paulson, ATP No. 642 and a former top-300 player, advanced via comeback 3-6, 6-4, 6-4 over Fabrizio Andaloro following a dominant 6-1, 6-0 qualy win over Federico Arnaboldi. No prior head-to-head exists; Callejon's No. 512 ranking and Spanish home support provide a marginal edge in this competitive round-of-16 matchup, with no injury concerns reported and trader consensus reflecting both players' recent Challenger-level upsets.
