Baseball's Unwritten Rules

Following the above hit by Toronto's Colby Rasmus, Texas pitcher Colby Lewis lashed out.  He claimed in an interview with MLB.com that it is unethical to bunt against the shift.  Unless I'm mistaken, the point of the shift is for infielders to gain an advantage by playing three of them on one side of the infield, and the point of batting is to get on base.  The idea that one part of the batter vs pitcher battle should not use all of their tools is absurd.  It's like asking a pitcher not to use a pitch because it's just to hard to lay off of in that situation.  Give me a break.

Don't want to be bunted against?  Field your position better.  Honestly this wasn't a spectacular bunt, had the third baseman been playing in his normal position who would've been expected to field that bunt?  The pitcher, Colby Lewis.
