The D-backs' No. 1 prospect (MLB No. 8) was injured while legging out a triple for Triple-A Reno on June 15.

RHP (right hamstring strain)
Expected return: TBD
Gallen threw a 31-pitch bullpen session on June 11 and a 37-pitch session on June 14. He is scheduled to throw a simulated game June 18. It's uncertain whether he will need another sim game after that. After throwing his sixth pitch of the game in the D-backs' 3-2 loss to the Mets on May 30, Gallen called over catcher Gabriel Moreno and wound up walking off the mound with a trainer. He was diagnosed with a strained right hamstring, which the club later announced as a Grade 1 strain. Gallen was placed on the injured list the next day. (Last updated: June 14)

Thomas has begun a rehab assignment in the Arizona Complex League and will likely move to Triple-A Reno to continue it.

He received a platelet-rich plasma injection to alleviate swelling on May 13.

Thomas injured his left hamstring when he grounded into a double play in the first inning on March 31 against the Rockies. He underwent an MRI exam on April 1 that showed a strain in the hamstring that was greater than a Grade 1, but not quite a Grade 2. (Last updated: June 14)
