NFHS Courtesy Runner

[chapmaja]

Yesterday we had a coach who wanted to use the same courtesy runner for both the pitcher and catcher (in different innings). This is still illegal based on what I recall. Is this correct?

I do have a question though based on something I saw earlier this season.

#1 starts as pitcher, #12 is the catcher. #14 courtesy runs for #1 in the first inning. #17 courtesy runs for #12 in the second inning.

In the fifth inning, #1 and #12 switch positions so #1 is catching and #12 is pitching. Are the courtesy runners locked into the position, or the player?

The position switching did occur this season, but not the courtesy runner part. I'm just asking this as a what if.
