I have too many of these to even write out here. The worst was at a local indoor baseball training center with both boys. I was in one cage with younger son picking up the baseballs to re-load the machine and 2016 was in the cage next to us hitting. I picked up a few balls along the side net, looked up to watch 2016 hit just as he hit a one hopper that hit me right in the eye through the net. Took me right out. Went down hard. I had an eye swollen shut with netting criss-cross patterns embedded for over a week.
I never wore a helmet coaching bases but re-thinking all the times I've been hit by a baseball here makes me think I should be wearing one all the time.
