PHOENIX -- The D-backs have spent the past few years trying to restock their farm system, particularly on the pitching side, after earlier trades had depleted their inventory.
With pitchers and catchers reporting Thursday, we continue our Spring Training preview with a look at some of Arizona's top prospects who will be in camp this spring. This is by no means an exhaustive list and it does not include third baseman Yasmany Tomas and right-hander Yoan Lopez, who were both profiled in the "new faces" installment of this series.
RHP Archie Bradley: Bradley competed for a spot in the rotation last spring, but after struggling in the Minors, he is likely headed back there to start 2015. He is still regarded as the organization's top prospect and is ranked No. 15 in MLB.com's Top 100 Prospect list.
RHP Braden Shipley: Another member of the MLB.com Top 100 (No. 39), Shipley will be in his first Major League camp. The righty is likely to start the year with Double-A Mobile, but he could see the big leagues at some point this year.
RHP Aaron Blair: A supplemental first-round pick in 2013, Blair is ranked No. 81 in MLB.com's Top 100 prospect list. Like Shipley, who was picked in the same Draft, Blair is making his first appearance in big league camp and is likely to start the year in Mobile.
3B Jake Lamb: Lamb, who is No. 80 on MLB.com's Top 100 prospect list, got an extended look during the final couple months of 2014, and he should battle Tomas for playing time at third base this spring.
C Peter O'Brien: Acquired by Arizona from the Yankees in the deal that sent Martin Prado to New York, O'Brien impressed the D-backs with his work during the Arizona Fall League. A hitter with prodigious power, if he continues to improve defensively he could be in the big leagues before the season is over.
3B Brandon Drury: Acquired in the Justin Upton trade, Drury has put up huge numbers in his first two seasons in the Minors with the D-backs. He has not been talked about as a candidate to make the big league team out of Spring Training, but Drury is another player who could be in Sedona Red sooner rather than later.
