Tszyu, the son of boxing legend Kostya Tszyu, dominated former world champion Tony Harrison to win the interim title in March. The 27-year-old Ocampo has 22 KOs in 34 wins, with his only losses coming against Errol Spence Jr. and Sebastian Fundora.

The Showtime announce team will call the fights remotely from CBS studios in New York City. 

Tonight’s Showtime tripleheader kicks off at 9 p.m. ET/6 p.m. PT and features hard-hitting Rolando “Rolly’’ Romero battling No. 1 Contender Ismael Barroso for the vacant WBA super lightweight world title in the main event from The Chelsea inside The Cosmopolitan of Las Vegas in an event presented by Premier Boxing Champions.
