8.4.2 SITUATION L:
With two outs, R2 on second base and R1 on first base, B5 singles. B5 passes R1 between first and second base (a) just before R2 touches the plate or (b) just after R2 touches the plate.
RULING: In (a), the run does not count, while in (b), it does count. A runner is called out at the moment he passes a preceding runner, but the ball remains live. Acts such as attempts of a runner to profit by running too far from the baseline to avoid a tag, or outside the three-foot lane while advancing to first, or running the bases in reverse, or other-wise making a travesty of the game may not be appealed. The umpire calls the runner out without waiting for the defensive player to call attention to the act."
That change and removal of 9.1.1M, confirms that FED is now with the other codes in making this a time play.
