At a state tournament this weekend, several questions came up. The team we played against had two girls with the same number...one shirt had the girls last name, the other just had the number with no last name. Umpire allowed this. Later, our pitcher was ejected from the game because her shirt became untucked while pitching. He claims he warned everyone before the game they would be tossed if their shirt was untucked.
Is there any such rule? and should there be two players wearing the same number?
