Answer
Baseball’s steroids scandal was a major controversy in Major League Baseball (MLB) in which many players, including Mark McGwire, were accused of using performance-enhancing drugs. The scandal began in 1998 when McGwire and Sammy Sosa were involved in a race to break Roger Maris’ single-season home run record. McGwire eventually broke the record with 70 home runs, but his performance was questioned by many, including baseball commissioner Bud Selig.
