[UmpJM]

ggk,

It depends on the rule code.

Under FED rules, the ball is immediately dead on a balk - so nothing after the balk "happened".

Under OBR rules, in your initial sitch (balk, F2 overthrows 2B in his attempt on the stealing R1, r1 ends up safe at 3B) the ball NEVER became dead as a result of the balk. Since the only runner advanced one base safely on the continuous action of the play immediately following the balk, the balk is disregarded - as if it never happened.

I believe that the issue that some posters on this forum have with the concept of "delayed dead" under OBR is that, in some cases, the ball NEVER becomes dead as a result of the balk. What is delayed is the umpire's decision as to whether or not to call "TIME!" because of the balk. Sometimes you do, sometimes you don't.

NCAA is like OBR rather than FED. In your NCAA sitch, the ball does NOT become dead when the F3 catches the pick-off throw, or at any other time during the play as described. Had the R1 been put out returning to 1B or had the F3 made a good enough throw to retire the R1 as he attempted to advance to 2B, THEN you would call "TIME!" and award the R1 2B on the balk.

You leave the ball "live" until you see if the R1 advances safely to 2B. Once he does, you disregard the balk. If the pitcher "aborts" as a result of the "That's a BALK!" call, you call "TIME!" and enforce the balk.
