6. Peter O’Brien C/1B: One of the newer additions to Arizona’s farm system is Peter O’Brien. Having seen him play in the AFL league this year, there are definitely parts of his game to like, such as his raw power. O’Brien’s power should play well in Arizona, as he hit 34 home runs between High A and Double-A last year. He could be a similar player to Mark Trumbo, but he doesn’t have the muscle Trumbo does, as he is a rather athletic guy. Most in the game think he profiles more as a first basemen rather than at catcher, but the Dbacks must feel differently given they don’t have an opening at first base. Look for O’Brien to get a mid season call up and add a boost of power in the Dbacks lineup.
