College game playing NAIA rules (OBR with modifications)
Scenario: In the 4th inning the DH draws a base on balls. Manager chooses to pinch run for the DH. The NAIA modifications allow each starter one re-entry, with the exception of the Pitcher and DH. In the 6th inning, the manager re-enters the original DH back in to hit. For the opposing teams benefit, does the opposing team coach need to wait for a pitch to be delivered to this illegal substitute to appeal, or does the illegal substitute simply need to take his place in the batter's box and the UIC put the ball into play?
