1999, Tampa Bay Devil Rays
Hamilton's well-documented journey to stardom is one of the most fascinating stories in the game today. The high school phenom was regarded as one of baseball's top prospects until a car accident prior to the 2001 season. After the accident, Hamilton started on a downward spiral into drug addiction. He was suspended for violating the MLB's drug policy and did not play baseball from 2004 to '06, going in and out of rehab attempts. The Reds scooped him up through the Rule 5 Draft in 2006. In 2007, he hit .292 with 19 homers and 47 RBIs in 90 games, but Cincinnati traded him to Texas. Hamilton continued to realize his immense potential in 2008, making his first All-Star Game (putting on an unforgettable show during the Home Run Derby), and 2010, winning the AL MVP award and batting title. In 2012, he appears poised to make a run at the Triple Crown after an otherworldly start: He's hitting .379 with a league-best 18 home runs and 49 RBI through May 23, 2012.
