Upon review, not listed per se as among the responsibilities for the scorer. However, the scorer is responsible for all recoding in the book, therefore the scorer is responsible for recording the actual wrestler who reports for the match. Even if a coach has written entries in the book, he/she may change their mind when it comes time for a wrestler to report.
It is the responsibility of the scorekeeper to enter the names in the scorebook, by rule. Sometimes coaches may provide a roster or fill in the scorebook, at their option.
