Speaking ASA
Top of the 2nd, S1 is told by the coach to take a position in RF, but did not notify the umpire.
In the 4th inning, this player fields a fair batted ball and throws out the tying run at the plate. At this point, the opposing coach visits the PU and tells him that the RF is an unreported substitute.
What action should the umpire take?
Ronald, please sit this one out
