Our unsung hero of 2015 is last season's rookie of the year, David Peralta picking up 42% of the votes, twice as many as any other candidate.
The story of David Peralta continues to be a remarkable one, that doesn't grow stale with retelling. A failed pitching prospect in the Cardinals' organization, he returned to his home country of Venezuela and re-invented himself as an outfielder. Returning the United States, he couldn't catch on with any franchise, so ended up signing for the Rio Grande Valley WhiteWings of the independent North American League - an organization which had already folded by the time Peralta made his major-league debut.
