Mark McGwire says he could have hit 70 home runs in a season without taking performance-enhancing drugs.
He tells The Athletic he regrets taking the drugs because he "didn't need to." McGwire hit what was then a record 70 homers in 1998 while with the St. Louis Cardinals. He is now the bench coach for the San Diego Padres.
McGwire said in a 2010 interview with Bob Costas that he used performance-enhancing drugs when he set the record.
