Major League Baseball's star witness against Alex Rodriguez, Anthony Bosch, is scheduled to appear on CBS television's "60 Minutes" Sunday night along with MLB chief operating officer Rob Manfred.According to a press release from the show, Bosch will say he personally delivered banned substances, including testosterone, insulin-like growth factor 1 and human growth hormone, to Rodriguez at least a dozen times and that A-Rod paid him $12,000 a month in cash.Rodriguez was suspended a record 162 games on Saturday as arbitrator Fredric Horowitz reduced the original 211-game ban. The ruling was a huge win for MLB even though the ban was reduced.The suspension would not have been possible without Bosch, the former Biogenesis chief who eventually cooperated with MLB's investigation. He provided the league with phone records and corroborated other evidence.Bosch's first public interview will air on Sunday night, as part of a 60 Minutes segment with Scott Pelley. Among his claims:-He personally delivered banned substances, including testosterone, insulin-like growth factor 1 and human growth hormone to Rodriguez at least a dozen times and Rodriguez paid him $12,000 a month in cash.-He personally injected Rodriguez because "Alex is scared of needles, so at times, he would ask me to inject."-Rodriguez's mission was to hit 800 home runs and that the Yankee slugger asked him for what he gave MLB superstar Manny Ramirez, a former Bosch client-Text messages obtained by 60 Minutes between him and Rodriguez indicate that at times they communicated daily about the substances the slugger took on his "protocol"-Says Rodriguez associates intimidated him to try to prevent him from cooperating with MLB in its investigation of the Yankee third baseman.Manfred is expected to tell Pelley that he believes threats against Bosch could be legitimate. He also denied a claim by Rodriguez's legal team that Bosch was given $5 million for his cooperation.A-Rod reportedly turned down numerous interview requests from 60 Minutes. His attorney Joe Tacopina said in an email that he had not been asked to appear.The segment will air on Sunday, Jan.12 at 8:00-9:00 p.m. ET on CBS.
