Proposed rule change: Rule 2.35 Look Back Rule: See Rule 8.7
Does that work?
Guess not...What you would do in the game is direct the coach to Rule 8.7, if she did not violate any article of that rule that is how you would explain that she is not out under that rule. I do see what you mean, if you take the rule literally, what can or cannot the runner "look back" at. BUT as WMB stated this rule was put into effect so the pitcher can look the runner back. Once she sees the runner returning to the last base touched the pitcher can begin to get ready for the next pitch, no need to worry about turning his/her back on the runner...by rule if they started back (after a stop) then they are required to return to that base. Again on the field if someone asks, your answer would be she did not violate the look back rule. If it is not stated that she can't look back at the coach then she can(your example)....as long as her feet don't do anything that violates the articles in rule 8.7 she is good!
