An illegal substitute may be discovered by the:

• A. Umpire.
• B. Home team.
• C. Visiting team.
• D. A, B and C.

Answer: (D)

Any illegal substitution can be noticed by the official or by either team, because enforcement rests with the umpire but observers from both sides are in position to see and raise the issue. The umpire officiates and can correct the lineup or apply penalties, but teammates and the opposing team may also notice that a player has entered or left the lineup illegally and bring it to the umpire’s attention. This shared responsibility helps ensure the game stays fair, so it’s possible for the illegal substitution to be discovered by the umpire, the home team, or the visiting team.
