Here is a look at the Arizona Diamondbacks top ten prospects following the trade deadline. To be eligible a player must meet the criteria for Major League Baseball's Rookie of the Year Award as well as not being on the current major league roster. Due to the second piece of criteria impressive power hitting first baseman Paul Goldschmidt is not eligible to make the list. Goldschmidt was ranked the number five prospect and was the best hitter in an organization without many big bats near the majors. Outfielder Collin Cowgill is also ineligible for being on the active roster.
Overall the Diamondbacks farm system is promising, especially the pitching. Not only does Arizona have plenty of pitching depth, but they have a group of high ceiling arms due to their two top ten draft picks of this year. Impressive returns on last year's trades of Dan Haren and Edwin Jackson have also contributed to their pitching prospect depth.
