Bernard Tomic defeated Valentin Vacherot in the first round of the ATP San Luis Potosí Challenger on clay on 25 March 2024. Tomic's victory marked a positive result in his efforts to rebuild ranking points through the Challenger circuit. The Australian, who has competed sporadically in recent seasons, showed enough to progress past the French qualifier. Vacherot, competing at Challenger level, was unable to capitalise on home conditions or secure an upset. The result provided Tomic with early momentum in the tournament as he looked to make a deeper run in Mexico.
