Protesting a ruling

Question
Who needs to make a protest? Must the head coach of the team make it or can a player/parent make it? I understand from previous messages it must be made before the next play - is that right?
THANKS

Hi Scott,

Here's ASA 9-2 look it over and write back w/ any questions

Section 2. PROTESTS. There are three types of protests:
A. Misinterpretation of a playing rule - must be made:
1. before the next pitch legal or illegal,
2. before the next play
3. before all infielders have left fair territory,
4. on the last play of the game, before the umpires leave live ball territory
B. Illegal player - must be made while the player in question is in the game and
before the umpires leave the playing field.
NOTE: A-B An umpire cannot reverse a decision after a pitch, legal or illegal.
C. Ineligible player - can be made any time. Eligibility is the decision of the
protest committee.
Section 3. Protests may only involve the interpretation of a rule.
Section 4. The manager, acting manager or captain of the protesting team shall immediately
notify the plate umpire that the game is being played under protest. The
plate umpire shall in turn notify the opposing manager and official scorekeeper. To
aid in the correct determination of the issue, all interested parties shall take notice
of the information, details and conditions surrounding the decision to protest.
