As an admitted baseball purist, all I can say is, you had that beanball comin'. You knew when you stepped in the box after the guy that bunts, or steals a base, with a 7 run lead, you had a target on your ribcage if you were lucky, on your chin if not. I don't condone it, but that's the way it is, especially with Latino tempers involved. I have a hard time believing Larry Walker was not involved in this somehow, being the hitter he was in MLB. I can see him pouring it on. I don't think Mexico is going to make it out of pool play, but if Canada is tied with somebody and it comes down to runs scored as the tie-breaker, I can see that, but you still have to know you're violating those "precious" unwritten rules. I think there's a place for the intentional HBP, but this is not it. Mexico should have sac'ed up and just worked on getting out of the inning. Funny how it took him 3 tries to hit him.
I don't know if there's some previous bad blood between the two, but there is now.
