Courtesy runner in ITB

[Cecil4]

#2 - a clarification on the USA Softball web site years ago - April 2014:

Play: In the top of the 8th inning, F2, who was the last batter to complete their turn at bat, is placed on 2B. The offense wants to put a Courtesy Runner in to run for F2. The umpires do not allow this because F2 did not bat and reach base safely.
Ruling: The umpires should have allowed F2 to have a Courtesy Runner. As long as F1 and/or F2 batted for themselves in the inning prior to the tie breaker and were the last to complete their turn at bat, they have earned the right to be put on 2B, therefore they can have a Courtesy Runner.

#3 - personal comment

BTW, there is also a rule that said the earning on base aspect excluded a DP or pinch hitter getting on base and then having the P/C as a runner. 8.10.e
