No. 1 MLB Draft Picks Since 1985

The catcher-turned-outfielder with light-tower power made his big-league debut earlier this season at only 19 years old. The story of the 6-3, 205-pounder is well known: He earned his GED after his sophomore year of high school so he could attend junior college for a season and be eligible for the draft a year early. Harper has done relatively well in the big leagues, hitting .267 with two homers and 11 extra-base hits in 24 games through May 23, 2012.
