46.02 Unlawfully Carrying Weapons
(a) A person commits an offense if he intentionally, knowingly, or recklessly
carries on or about his person a handgun, illegal knife or club.

Uh, I wonder why baseball isn't illegal here.

Sec. 46.01. DEFINITIONS. In this chapter:
(1) “Club” means an instrument that is specially designed, made, or adapted for the purpose of inflicting serious bodily injury or death by striking a person with the instrument, and includes but is not limited to the following:
(A) blackjack;
(B) nightstick;
(C) mace;
(D) tomahawk.

Thus a baseball bat is not a club. However case law has defined that an item used with the intent of bodily injury qualifies as a club even if not manufactured initially with that intent. So if you rob a store using a baseball bat as a threat, it would now qualify as a club and be against the law...similarly if you go over to your neighbor with your bat in the heat of an argument, you could be charged under unlawful carry of a weapon. That is assuming you are not arguing about a backyard game of baseball :)
