Which logical fallacy is used in the text?
Every major league baseball player hits with a wooden bat. So, to improve my hitting, I've switched from an aluminum bat to a wooden one.

 - straw man: a misrepresentation of an opponent's position that makes it easier to argue against
 - false causation: the assumption that because two things happened together, one caused the other
 - circular reasoning: an argument that supports a claim with the claim itself
The text argues that because professional baseball players hit with a wooden bat, the speaker thinks her hitting will improve if she switches to a wooden bat. However, this is not necessarily true. Professional baseball players hit with a wooden bat because it's required by the rules of professional baseball. So, they aren't professional players because they use a wooden bat. Rather, they use a wooden bat because they're professional players. This illustrates a type of logical fallacy known as false causation.
