Right fielder Ryan Church, who has suffered two concussions this season and recently spent more than three weeks on the DL because of post-concussion syndrome, left tonight’s game in the eighth inning after complaining of dizziness. 11:05 P.M. UPDATE: The Mets and Church said the dizziness was related to migraines he has suffered since high school and not to the concussions. He is listed as day-to-day.
