It was widely believed that top prospect Archie Bradley would spend most of the 2014 season in the major leagues, but an elbow injury in late April cut into his development and forced the organization to reassess his timeline. The right-hander looked better in this year’s Arizona Fall League, but he’ll still have some questions to answer in the upcoming season.

Braden Shipley, the No. 15 pick in last year’s draft, proved to be a first-round steal with a plus fastball-changeup combination, impressive athleticism and better than expected command. The team’s Compensation Round A pick from last year, right-hander Aaron Blair, has also been impressive this season, as he dominated at three levels, including Double-A.

The Diamondbacks landed another potential steal this year when Touki Toussaint fell in their lap at No. 16 overall, followed by ultra-athletic outfielder Marcus Wilson in compensation round B.

22-year-old Brandon Drury, who was acquired from the Braves in the Justin Upton deal, has a good eye at the plate, makes a lot of contact and has grown into some power. The same applies to 243-year-old third baseman Jake Lamb, who received a promotion to the major leagues in August after raking at Double-A Mobile.

The Diamondbacks also have a pair of promising, switch-hitting teenage middle infielders in Domingo Leyba (19), who came over from the Tigers this offseason in the Didi Gregorius trade, and shortstop Sergio Alcantara (18), who has an incredibly advanced approach for his age to go along with the defensive chops to stick at shortstop.

Here are the Arizona Diamondbacks‘ top 10 prospects for the 2015 season.
