The following is not directed at anyone, just a reflection (that I reserve the right to be wrong about).
Just to be clear about the rule/consequences of the rule: when getting no hit, you should make it easier to continue to be no hit. After all, it's the polite thing to do and you might get thrown at if you don't believe it's your obligation to make it easy on the pitcher to embarrass you.
There are times when throwing at a guy is not justified, but just a whining/temper tantrum by the pitcher. I think this would be one of those times. If you were the next batter (HBP) and asked the pitcher 'why'd ya do that?'
What possible rebuttal could the pitcher give without sounding childish/whinny? "you weren't supposed to do that?"
Furthermore, say it's a 7-0 no-hitter in the bottom of the 8th... I'm guessing that most would think the rule applies then.
Span bunts his way on, and Carroll get's beaned in retaliation. YOu've got two on, 0 out and Mauer up. It's possible to win this game yet, no? So we'd have to be talking about a 9th inning 10-0 no hitter to be sure of a loss... even then, I think this rule is silly... just my opinion (and reasons)... you don't have to agree.
