The sudden and sad happening

In Minor League's game of 2A Talsa which is a subsidiary of Rockys, a batting coach, Mike Clueboe, died by foul-ball hitfing to his dead. Though he was carried to hospital at once, he died in the hospital.
He played 44 games as a major leaguer. He entered the team just on 3rd, July.
It is said only unlucky or tragedy. As a same sports player, I feel like running away.
