LaRoche played shortstop for Grayson County College(he also played for the Keene Swamp Bats of the New England Collegiate Baseball League) and became the top position-player prospect in the Cape Cod League. He had been originally a catcher but was injured and told to go to a different position because of that. He was originally drafted in the 21st round by the San Diego Padres in 2002, but he turned down an offer estimated at $200,000 and remained in school for another year before re-entering the draft the following year. Despite breaking a bone in his left leg in a collision while playing first base, his stock soared and scouts projected him as a first rounder.
