Not just that, deliberately taking out a defender should be at the very least an automatic out, and I would seriously consider an ejection as well. There's breaking up a double play the hard way, which is sliding aggressively into the bag, but what Utley did is completely uncalled for and should not be allowed.
Edit: and I do see the concern with even just trying to break up a double play the "clean" way, as Hurl continually argues. The line between what constitutes fair and dirty is pretty thin, and clearly is not enforced. I'm all for not losing star SS or 2B in a play like that.
