I’m not even going to say a word about the possibilities here: I’m going to leave that up to you folk in the comments. I will simply stick to listing the potential candidates. So here are the 12 position players and 7 pitchers to appear for the Diamondbacks this year, who qualified as rookies (according to Baseball Reference anyway). I’ve listed them in descending order of the number of games in which they appears for the position players, and innings for the pitchers. The link for each category goes to a chart listing the main stats for them.
