The short list to land a shot at unified heavyweight titlist Anthony Joshua on June 1 at New York's Madison Square Garden has a new name: Mexican contender Andy Ruiz Jr., Matchroom Boxing promoter Eddie Hearn told ESPN on Monday. Ruiz (32-1, 21 KOs), 29, of Imperial, California, entered the picture after scoring a fifth-round knockout of Alexander Dimitrenko on Saturday night in Carson, California, after which he said he was interested in fighting Joshua. The win was Ruiz’s third in a row since losing a majority decision to Joseph Parker for a vacant world title in December 2016. Parker was later outpointed by Joshua in a unification fight. Hearn said other potential opponents are Luis Ortiz, Michael Hunter and secondary titlist Manuel Charr with interim titlist Trevor Bryan and European champion Agit Kabayel further down the list. Joshua needs a new foe because Jarrell “Big Baby” Miller failed multiple drug tests last week.
