Grady Sizemore

After he appeared on the cover of Spirts Illustrated in his fourth season, Indians’ general manager Mark Shapiro called Sizemore “without a doubt one of the greatest players of our generation”. Well, through his first five seasons, Sizemore was thrilling: he averaged 96 runs, 34 doubles, 22 homers, and 23 steals, while slugging nearly .500 for the Indians. Sizemore was an All-Star three times and won two Gold Gloves in his first four full seasons. But two serious knee injuries (one to each leg) sidelined Grady and hampered his trajectory to superstardom. He never played a full season after the age of 25, and retired when he was 32 years old.
