Verbal Obstruction??

[Buck912]

As a follow up to the topic of verbal interference, what about verbal obstruction? This is quite coincidental but this topic was brought up and discussed at length last night at our association meeting. I happen to be the one that brought it up. Several in attendance did not agree with my opinion and others just "scratched their heads" with "I don't know what'd I do" answers. Here's an example....R1 on 1st base and stealing on the pitch. The pitch to the batter is "foul tipped" and while the runner is advancing, the defensive player or coach from the dugout is shouting "foul ball." At this time the runner stops and starts to retreat and subsequently tagged by the defensive player. I know that it's the player's responsibility to be alert as to what's happening in the game (which was the most popular answer in last night's meeting) but at the same time I feel this is a classic example of verbal obstruction. If I'm wrong, then someone please give me an example of a situation involving verbal obstruction? I've just completed my 3rd year of high school ball and will be doing college ball this year and I still consider myself a rookie, so I spend a great deal of time reading the rules & case book to be comfortable with my game, so all replies will be appreciated.
