SAN ANTONIO By the time Mario Barrios enters the ring as the world champ, it would have been almost 365 days since he won that title. On September 28, 2019, Mario Barrios defeated Batyr Akhmedov by unanimous decision to win the WBA World Super Lightweight championship belt. The Barrios vs. Karl fight will be one of four title fights on the Showtime/Premier Boxing Champions PPV card. Barrios told KSAT 12 Sports last year that he was more than willing to give Akhmedov the chance to fight him again. Karl is currently on a three-fight knockout streak after losing his second professional fight by technical knockout in 2018.
