CR reported but not in game

[shipwreck]

Had a game yesterday and this happened. I was BU. Coach reported to PU and he announced that CR would come in and run for pitcher. After an out was recorded, the OC discovered that the CR had not taken the pitchers position on first base. Isn't the PU lineup the official line-up? It showed the CR should be on first but wasn't. I was thinking that since CR was the one that should be there and pitcher couldn't replace CR on base, this should maybe be treated as an illegal substitution even though an illegal substitution hadn't taken place. If this was an illegal substitution, the offended team could notify the PU or an umpire without the offended team notifying him could rule on it. What do you think? Dave
