What's the Call

[MGKBLUE]

Under rule supplement 36 the umpire will need to judge whether the runner committed another violation and that violation is being played upon.

The example given in the rule supplement is as follows:

A runner leaving second base too soon on a fly ball is returning after the ball is caught and is obstructed between second and thrid base. If the runner would not have made it back to second base prior to the throw arriving, the runner remains out.
