Tsitsipas boosted trader consensus with a commanding 6-2, 7-5 upset of No. 11 seed Alexander Bublik in round two, his finest showing in months and signaling clay-court revival on a surface suiting his one-handed backhand and past Madrid success. Local 21-year-old Merida, on a qualifier surge past Corentin Moutet, benefits from home crowd energy and high-altitude bounce, but lacks Tsitsipas' Masters 1000 pedigree; no injury concerns reported for either ahead of the April 27 matchup.",
