Diamondbacks Official Opening Day Roster Revealed

The Arizona Diamondbacks have officially announced their opening day roster ahead of Thursday's season-beginning showdown with the Los Angeles Dodgers.

"I'm really excited about the 26 guys that we do have. We're ready to go out and compete," manager Torey Lovullo said on Monday.

Below is the Diamondbacks' complete 26-man roster:

Designated for assignment:

RHP Grant Holman

Placed on the 10-day Injured List:

C Adrian Del Castillo (retro. March 22; strained left calf)
INF Tyler Locklear (retro. March 22; recovery from left elbow surgery)
OF Lourdes Gurriel Jr. (retro. March 22; recovery from right ACL surgery)

Placed on 15-day Injured List:

RHP Merrill Kelly (retro. March 24; left intercostal nerve irritation)

Placed on the 60-day Injured List:

RHP Cristian Mena (strained right shoulder)
LHP Blake Walston (left ulnar collateral ligament surgery)

In terms of injuries, the D-backs already anticipated both Adrian Del Castillo and Tyler Locklear being unable to make it on the field come opening day. Lourdes Gurriel Jr., who is racing back from ACL surgery, may only miss about one month, though that timeline is not official.

Merrill Kelly is expected to make a pair of rehab starts, including one in Triple-A Reno, before hopefully rejoining the D-backs' rotation at during the second road trip of the regular season in early April.

The disappointing news on the injury front is Mena, who was expected to be one of Arizona's top depth options for their starting rotation — a rotation that is now one injury away from being in serious trouble.
