In a State game, the opponent put in a courtesy runner that was not listed on the official line-up card. This is after the umpire went to great lengths to verify with both Managers that the lineups submitted were correct, including subs. Once the runner was put in, our scorekeeper noticed that the player was not listed. The plate umpire and the field umpire discussed, and after 5 minutes requested an UIC to come to the field to answer the question. After approx 10 minutes, and the UIC going to the ASA table to check the official Roster, it was determined that this player was on the roster but was not on the line -up. What should the ruling have been? And should the official game clock have been stopped during this time, since the Umpire didn't know the ruling himself?
Just curious, wanna get this straight before getting into additional important games this Summer.
