I don't recall it even being discussed. I may be wrong...maybe someone in some state office proposed this as a rule change. If they did, their proposal did not come close to passing (as evidenced by the fact that I don't recall it even being discussed.) For what its worth, I'm a baseball purist. I still hate the DH rule (and that rule came in to effect before I was born). So, there's no hope of anyone convincing me to vote for such a proposal.
As an aside, I love the fact that nearly a decade later, I was the home plate umpire for a legendary 15-inning state semi-final game that is still talked about in prep baseball circles in SC all these years later. Both teams scored a run in the first inning...and couldn't score again. Combine that with the fact that it was being played between arch-rivals, to advance to the state championship, and that it ended on a freak bad bounce on an infield ground ball hit to F3 (with an R2, and two outs)...has led to this game taking on legendary status. During the game, I never wanted it to end. Seriously, I actually starting thinking, "it would be awesome if we could break some state record for longest game." The AD for the school that had to pay us actually came in to the locker room after the game and shook our hands and told us that we had done such a good job that he was paying us two game fees! I wouldn't want to ruin the possibility of that never being able to happen again by having an International Tie-Breaker Rule. That is one of my few games, at any level of baseball, that I still go to bed day-dreaming about.
