You make the call

[RKBUmp]

Obviously different rule set, but still a case play covering a very similar situation and explanation for the call and why it should be called. When umpires start determining "intent" of the rule and if an advantage was gained or not it becomes their own personal interpretation of the rules. When that happens rather than calling the game per the published rules, it becomes literally thousands of different rule sets based on each umpires own personal interpretations of intent and gaining an advantage.

Look-Back Rule
Runner on first base following a single. The pitcher has possession of the ball in the circle when:
1) with only a single foot on the base, the runner lifts it off the base to clean off the bottom of her cleats, thus breaking contact with the base. She does not attempt to advance so because there is no advantage gained, should the umpire ignore the violation?
2) the runner walks off the base to groom the dirt area which she churned up as she ran out her single. She does not attempt to advance so should the umpire ignore the violation?

Ruling
1) No, the runner should be called out unless she asked for and was granted time by the umpire.
2) As in the earlier situation, the runner should be called out unless she asked for and was granted time by the umpire.
In both these cases, the umpire should enforce the rule without assigning intent of the runner or whether or not an advantage is gained. It is much cleaner to call all aspects of the game based on the objective actions that are displayed rather than to assign value or intent and then decide if the action warrants a penalty. For some, that might seem “nitpicky” but it does provide predictable, consistent application of the rules without having to judge intent OR whether or not a “real” advantage is gained. That said, it is good preventative umpiring to anticipate these possible actions. For example, if the area around the base is churned up at the conclusion of play, the umpire can signal “time” in anticipation of the player’s desire to smooth the ground. If the player then simply walks off the base without requesting time, you have no violation as play is already suspended. Bottom line, however, is that players are responsible for adhering to the playing rules and the rules committee does not favor the slippery slope of ignoring rule violations when there’s no intent to violate the rules or conversely only penalizing players when they intentionally violate the rules.
