6. Maris Breaks Ruth's HR record
Before the steroid era plagued the baseball history books, Roger Maris broke Babe Ruth's single-season home run record in 1961 with some controversy of his own. Eclipsing the former total by only one, in eight more games than it took Ruth to set his record, Maris nonetheless set a new high in homers with 61. Thirty-seven years later, Mark McGwire and Sammy Sosa (and later Barry Bonds) visited the pharmacy on the way to the ballpark and topped Maris' mark. For many Maris' 61 is still the real and honest mark, and there's no conversation—it would just be like comparing apples and pesticide-contaminated oranges.
