Condolences to his family & I've got 2 words for anyone playing any recreational sport regularly...life insurance.
I guess a guy went down sat in a local tourney of heat exhaustion but you never know. Had a guy get smoked in the back of the head @ home on a cutoff throw from the ss 2 weeks ago in a game I was umping...luckily he's fine. Saw a guy get hit in the head going into 2nd last week...guess he was ok & continued. A few years back @ military worlds pcb a guy on the team we were playing collapsed into a seizure when he hit the of grass,glad we had med folk on our team. Turns out he had some problems w/ sugar & the heat wasn't helping.
The stories are out there every year,hopefully it never happens to you but make sure your family has some security.
And, no I'm not an insurance agent.
