Zac Gallen Scheduled for Wednesday Bullpen Session to Test Shoulder

Arizona Diamondbacks ace Zac Gallen is expected to take the mound for a bullpen session this Wednesday. Gallen has been dealing with shoulder issues, and this upcoming session will serve as a critical test of his recovery progress. Steve Gilbert of MLB.com reports that the team is looking for positive signs from the right-hander as he works toward returning to the rotation. His health remains a top priority for an Arizona pitching staff that relies heavily on his veteran presence and arm.
