Rule 7.08e reinstated force play

[SAump]

A tag must be applied.

Here is the situation: Runner on first, one out. Batter bunts and beats out the throw to first. R1 rounds 2b. As F3 throws to F6, R1 slides back into 2b but overslides it (unintentionally)(to the 1st base side of 2b). F6 steps on 2b before R1 retouches 2b, but does not tag the runner.
Is the runner out via rule 7.08e?

B/R occupies 1B. R1 may not return to 1B. If R1 returns immediately to 2B, then a tag must be applied. If R1 makes no attempt to return to 2B, enforce 7.08e.

Ruling: Safe.
