Mark McGwire became a household name in 1998 during his historic home run race with Sammy Sosa. That year, McGwire smashed an incredible 70 home runs, shattering Roger Maris’s long-standing record of 61 from 1961. McGwire’s towering homers and physical power captivated baseball fans around the world. However, his mark was later surpassed. Despite the controversy that followed due to admissions of performance-enhancing drug use, McGwire’s impact on the game is undeniable. His rivalry with Sosa brought excitement back to baseball during a time of dwindling fan interest. While McGwire did briefly hold the record, he does not currently sit atop the all-time single-season home run list. That title belongs to another slugger who took power hitting to a whole new level.
