In 1998, Mark McGwire broke the single-season home run record in Major League Baseball, hitting 70 home runs. This remarkable achievement sparked significant interest in the sport and led to discussions about performance-enhancing drugs in baseball. McGwire's pursuit of the record, along with Sammy Sosa's competing campaign, became a focal point of the season, captivating fans and reviving enthusiasm for the game. The record was later surpassed by Barry Bonds in 2001, but McGwire's achievement remains iconic in baseball history.
