"It was just unbelievable to see that," Liberal manager Adam Anderson told the Eagle. "The strength of Chad and his family has rubbed off on our organization."

Kaiser, a batboy for the Bee Jays, was struck in the head Saturday during a National Baseball Congress World Series game against the San Diego Waves. The Eagle reported that Kaiser, who was wearing a helmet, was struck by a follow-through swing near the on-deck circle. The home-plate umpire, who is also a paramedic, treated the boy until an ambulance arrived and took him to the hospital.

"With the permission of the family, and with much sorrow and a very broken heart, I regretfully inform everyone that Kaiser Carlile passed away earlier this evening," the team said, according to CNN. "Please keep his family and our team in your thoughts and prayers."

"He really gained 30 big brothers this year, and there are 30 guys on our team right now who are grieving this loss," team spokesman Roy Allen told the Post.

"He was our teammate," added pitcher Kadon Simmons. "He was our spark plug. Without him, no one would run; we'd have no energy."
