12:30PM Update: Per the fire chief on scene, the fire started in one of the suites at around 11:00AM, and has spread through the stadium via the attic. The sprinkler system apparently has not been able to extinguish the flames.
The firefighters are fighting the fire from afar, as the structure was deemed too unsafe for anyone to approach on foot.
Late this morning, reports started coming from Grand Rapids news that Fifth Third Ballpark had caught fire. The blaze quickly picked up and is doing severe damage to the stadium.
