How about this.... F1 has been cruising and after a HR, he blows up? Not a very good pitcher, I guess.
It's not for us to decide if F1 is having a problem or not. As I said, if he was cruising along and a HR results in a HBP,
that is a problem that will go from simmer to boil quicker than you know.
I agree with a warning
at any level and once the warning is given, the next hit batsman is a ticket out of the park.
