Brandon Drury 1B ARI 1 Day

Drury will split time between second and third base this spring, the Arizona Republic reports.

Defensively, Drury stands to benefit from the added versatility as there is a potential road block at third base if Yasmany Tomas proves capable of sticking at the position. Drury played a few games at second base during the Arizona Fall League, but he'll likely go back to Mobile to begin 2015 before continuing his ascent through the system at Triple-A Reno.

Corey Dickerson LF COL 1 Day

Dickerson is in line to open the upcoming season as the Rockies' regular left fielder, MLB.com's Thomas Harding reports.

When injuries to Carlos Gonzalez and Michael Cuddyer opened up a regular lineup spot last season, Dickerson took full advantage, batting .312/.364/.567 with 24 homers, 76 RBI, and eight stolen bases across 478 plate appearances. The allure of a full-time role in 2015 has Dickerson holding down a high spot on fantasy draft boards, but there's still a chance he or Charlie Blackmon could fall into a platoon with Drew Stubbs, given both outfielders' unimpressive career numbers against lefty pitching. That being said, any at-bats Dickerson may lose against lefty pitching or struggles he may have when used in such scenarios should be mostly negated by playing half his games at Coors Field, which will likely enable him to uphold a lofty batting average once again.

Ender Inciarte LF/CF ARI 1 Day

Inciarte's role to begin the season is somewhat uncertain as the Diamondbacks are still working with Yasmany Tomas at third base to begin the spring.

If Tomas can handle third base, Inciarte and David Peralta will likely share time in left field. Both players are left-handed hitters, however, which rules out a platoon. In the event that Tomas can't handle the defensive rigors of third base, Inciarte and Peralta stand to lose their path to regular playing time, while Jake Lamb would slot in at third base.

David Peralta OF ARI 1 Day

Peralta's role to begin the season is somewhat uncertain as the Diamondbacks are still working with Yasmany Tomas at third base to begin the spring.

If Tomas can handle third base, Peralta and Ender Inciarte will likely share time in left field. Both players are left-handed hitters, however, which rules out a platoon. In the event that Tomas can't handle the defensive rigors of third base, Peralta and Inciarte stand to lose their path to regular playing time, while Jake Lamb would slot in at third base.

Jake Lamb 3B ARI 1 Day

Lamb has reported to camp in great shape while opening the eyes of new manager Chip Hale, according to Fox Sports Arizona.

Yasmany Tomas is still getting a look at third base, and a decision regarding his ability to handle the position defensively should be made in the middle of March. If Tomas has to play the outfield, Lamb may be the primary starter at third base for Arizona, likely on the large side of a platoon. In the event that Tomas sticks at third, it's possible that Lamb will be optioned to Triple-A Reno to receive everyday at-bats.

Aaron Hill 2B ARI 1 Day

Hill is competing to serve as the Diamondbacks' starting second baseman during spring training, Fox Sports Arizona reports. "The best guy plays every day," D-backs manager Chip Hale said. "If Aaron Hill comes in and he is back to Aaron Hill that his baseball card says on the back . . . If he's the best guy at that position, he'll be our second baseman."

Last season, Hill played through a wrist injury that led to a significant drop in his OPS. In addition to being healthy as spring training has started, Hill shed five pounds during an offseason workout regimen this winter. Defensively, his skills have also shown signs of tarnish, but it's expected that the Diamondbacks will be more inclined to shift their defenders under new manager Chip Hale, which may help slow that decline. At a significantly reduced price, Hill offers some value given his potential to bounce back assuming better health in 2015.

Robbie Ray SP ARI 1 Day

Ray is part of a large competition for one of the final three spots in the Arizona rotation to begin the season.

Most likely, he'll head back to Triple-A to begin the year, but Ray is competing with Chase Anderson, Allen Webster, Rubby De La Rosa, and Vidal Nuno, among others, while the team's top prospects and a couple of injured starters will all join the mix at some point this season. Considering that he's still just 23 years old and that he still has minor league options remaining, Ray is a reasonably good bet to get bumped down as organizational depth to begin the year.

Vidal Nuno SP ARI 1 Day

Nuno is part of a large competition for one of the final three spots in the Arizona rotation to begin the season.

After being acquired from the Yankees for Brandon McCarthy last summer, Nuno pitched well for the Diamondbacks (20.3% K%, 5.9% BB%, 3.76 ERA, 1.09 WHIP). His chances to keep a rotation spot took a significant hit with the addition of Jeremy Hellickson, Allen Webster, Rubby De La Rosa, and Robbie Ray via trade during the offseason. Further, the team has a slew of prospects on the brink of joining the big league club, so Nuno figures to have a short leash even if he emerges with one of the three available spots leading into Opening Day.

Allen Webster SP ARI 1 Day

Webster is not a lock for the Diamondbacks' rotation to begin the season, but he may have a leg up on the open competition for one of the final three spots behind Josh Collmenter and Jeremy Hellickson.

With increased depth, the Diamondbacks should have plenty of competition for rotation spots throughout the season. Webster pitched well in September for the Red Sox to close out 2014, and he'll need to sustain the improved control he showed down the stretch order to keep a starting gig regardless of when that opportunity is afforded him by his new club.

Rubby De La Rosa SP ARI 1 Day

De La Rosa is not considered a lock for the Arizona rotation to begin the season, but he is leading candidate to handle one of the three open spots behind Josh Collmenter and Jeremy Hellickson.

With a long list of options in camp vying for the three available spots, and the potential for prospects Archie Bradley, Braden Shipley, and Aaron Blair to push their way into the mix at some point in 2015, De La Rosa will have to pitch well in order to secure a spot regardless of whether he breaks camp as a member of the rotation, or has to wait for one of his counterparts to struggles. Thus far, the Diamondbacks haven't provided any indication that De La Rosa would shift to the bullpen if he fails to begin the year as a starter.
