2. Alex Rodriguez's Record-Setting Suspension
In 2009, A-Rod admitted that he had used steroids and also tested positive for banned substances in 2003 when he was a Texas Ranger, before MLB rules had any penalty against the infraction. By then, he'd already signed a 10-year, $275 million contract with the Yankees. Already a polarizing player, he was one of 14 players suspended this year for his alleged part in the Biogenesis performance-enhancing drug scheme, receiving an unprecedented 211-game suspension. If the 38-year-old's appeal of the penalty fails, it will be the longest suspension in MLB history aside from a lifetime ban, and could very well end his playing career.
