But the impact lasts longer than a game. The bullpen is taxed, so the next game we have to run the starter longer. I'm not saying any pitcher is breaking just because of lengthy games...like you said, it doesn't happen frequently enough. But I just don't see the upside. What's to gain? By the 13th inning, fans are just ready for it to be over...players are tired...call it a tie and move on. Save the marathon games for the playoffs, like hockey does. By this logic MLB should also have a slaughter rule to shorten games to 5 innings if one team is up by 5 runs or w/e. This is a solution in search of a problem. Nah, that happens far more often, and would have a much larger impact. This is a change that would be to what you already showed was a very small number of games.
