A 9-year-old who was hit with a bat during a baseball game in Kansas over the weekend has died.

Kaiser Carlile, a batboy for the Liberal Bee Jays team, was accidentally struck Saturday at a National Baseball Congress World Series game.

“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 in a statement.

“Please keep his family and our team in your thoughts and prayers.”

Kaiser was a batboy for the team, which is a summer league for college players.

One of the batters accidentally hit him during a warmup swing as the boy was retrieving a bat, according to team president Nathan McCaffrey.

McCaffrey said he heard the bat collide with Kaiser, who was wearing a helmet, before he took a few steps back and fell.

“Just to see him fall, that’s what crushes you,” he said.

The Bee Jays went on to win the emotional game over the San Diego Waves 12-5 in 13 innings.
