What responsibility does the Libero Tracker have during the match?

The role of the Libero Tracker during a volleyball match is specifically focused on tracking the participation of the libero in sets. This includes monitoring when the libero enters and exits the match, ensuring all substitutions involving the libero adhere to the rules and regulations of the game. This task is crucial as it helps maintain the integrity of the match and ensures that the players are substituting correctly.

When the libero substitutions are tracked accurately, it helps prevent violations related to the substitutions that could potentially impact the team's performance or lead to penalties. The Libero Tracker does not have the authority to request more timeouts or notify the referee of illegal substitutions, as those responsibilities are usually managed by the coach or head referee. The main focus is purely on tracking the libero's participation, which underscores why this answer is the most accurate and appropriate.
