Happened a couple days ago. Batter gets a base hit. He reaches first and has someone run for him. Two batters latter he goes into game to run for someone else (in the same inning). My contention is (and not sure of rule) that a player can not be used as a runner when he himself was run for. I could be wrong, if I am please let me know.
MV ... Your contention is correct ...
