So true on Giambi sliding. The play is not made if he slides. I am not sure if the on deck hitter was helping him there, but when in doubt, he should slide.
I think it's an easier out if Jeter doesn't touch the ball. The throw would have gotten to the catcher quicker and was on line.
However, regarding the OP, I don't have a problem with Jeter faking the HBP. He was doing what he was supposed to, which is get on base. All that old-timey "respect the game" stuff is crap. He did his job. I'd be ****** if one of the Cubs had the same situation happen to them and they admitted it didn't hit them.
