Brock Holt has been out of the Red Sox lineup since April 22 due to vertigo symptoms. He’s spent more than a month on the disabled list battling the condition, making 14 appearances for Triple-A Pawtucket despite recurring symptoms.
The plan was to have Holt work through the condition in game situations, as a way of potentially acclimating to the feeling. Instead, the condition proved relentless as he hasn’t been able to adjust or regain any measure of his previous form, hitting just .217 at Triple-A. The consistency of his condition led the Red Sox to consult Michael Collins, a sports concussions expert at the University of Pittsburgh.
