Ok, Lemme start over....I will explain it better this time...I promise!
The catcher leads off the inning with a single.
#8 is the courtesy runner for the CACTCHER.
The next batter is the PITCHER who is HBP and injured. #8 advances to 2B and a runner runs for the PITCHER at 1B. (Pinch runner or Courtesy runner, it does not matter)
Now, the Offensive Coach realizes that #8 needs to warm up to pitch and he sends in a pinch runner for her at 2B.
My partner and I looked it up after the game and could not find anything to address this. the NFHS book says that there can be no "courtesy runner" for a courtesy runner. I have never seen a pinch runner for a courtesy runner but, since I knew of no rule that forbids it, I allowed it.
Did I do it right?
