SAN ANTONIO – Amilcar Vidal proved his readiness Saturday night at least for legitimate middleweight contenders.

The unbeaten Uruguayan showed some defensive flaws, but he beat his best opponent to date, Immanuwel Aleem, by majority decision in a closely contested, 10-round, 162-pound bout on the Jermell Charlo-Brian Castano undercard at AT&T Center. Aleem became just the third opponent to take Vidal (13-0, 11 KOs) beyond the second round, the second opponent to go the distance with him and produced some strong moments of his own.

The game Aleem’s efforts still weren’t enough to sway the judges in this fan-friendly opener of this “Showtime Championship Boxing” tripleheader. Judges Ruben Carrion and Glen Crocker scored Vidal a 97-93 winner, and Anthony De Los Santos scored the action even (95-95).

Vidal scored three straight first-round knockouts against unbeaten opponents before he met Aleem, who was more experienced against experienced opponents. Vidal’s body attack slowed down Aleem at times, but the shorter, stouter Aleem took Vidal’s power well overall.

Aleem (18-3-2, 11 KOs), of Richmond, Virginia, still slipped to 1-2-1 in his past four fights. Vidal joined Hugo Centeno Jr. and Ronald Ellis as opponents who’ve beaten Aleem, who also has draws with Matt Korobov and Demond Nicholson on his record.
