Every season, there are prospects that seemingly come out of nowhere to post monster numbers in the minor leagues—take Darin Ruf, for example.
Heading into the 2012 season, Ruf, who was 25 at the time, had yet to play in a game above the High-A level but was coming off a career-high 17 home runs. Then, in his first taste of Double-A, Ruf exploded for a minor league-leading 38 home runs last season, while also adding three more as a September call-up with the Phillies.
