Athlete: Mark McGwire
: Baseball
When: 1999

The home run race between Sammy Sosa and Mark McGwire captured the nation. Everyone was keeping track of their progress while they chased Roger Maris' record of 61 homers in a season. On September 8, 1998, Big Mac took a pitch from the Cubs' Steve Trachsel and snuck it over the left field wall for No. 62. McGwire's record of 70 home runs in a single season would only stand for a couple years until Barry Bonds hit 73 dingers just three seasons later.

But everything he accomplished would soon fade away in 2010 when McGwire confessed to "using steroids on and off for a decade." The relationship between himself and the people of St. Louis has improved since that time as Mac currently serves as the team's hitting coach. One of the best steroid users in baseball history? No doubt, son!
