Q.Among this latest incident, the pop-up in Toronto and the slap against Boston, has Rodriguez become the king of breaking the game’s unwritten rules? A.The only guy in A-Rod’s class is A.J. Pierzynski — who also makes a habit of crossing over pitcher’s mounds. The primary difference between A-Rod and A.J. is that Pierzynski is devious; everything he does on a ball field is calculated. He’ll cross close enough to the pitcher to actually brush him — nothing so obvious as a bump, but enough to tick the guy off. It’s all designed to take the pitcher’s focus off the hitter. I don’t give A-Rod that much credit.
