illegal substitue.

[Gre144]

An illegal substitute bats and gets on base. The next batter gets up and hits a single. The defesive coach appeals batting out of order on the batter who followed the illegal substitute. I guess my question is who would be the batter that should legally follow the illegal substitute? (I would imagine that it would be the person who follows in the line up the person that the illegal substitute substituted for. Am I right?)
