As a catcher, myself, I think it's pretty weak of Pujols to try that. That's intent to injure. I accept contact at the plate as much as anyone (in fact, I encourage it) but if you're going to run through the catcher be a man about it and go high. If you're intent is to slide you should avoid the catcher.
This is especially disappointing because I really like Pujols and Pujols is a big enough guy that he shouldn't have to resort to this stuff.
By the way tom, LOVE the new avatar and sig. Gun to my head I'd have to name "O Brother..." as my all time favorite movie.
