If the intent is to get a pitcher to not have to pitch to batters 3x a game, that also means that your starter/primary pitcher is going to pitch less innings.
If this concept becomes accepted throughout the league, it seems to me that it will eventually change pitching as we know it.The eventual result to me is pitchers pitching once through the order, ie, 2-3 innings.So the team would need 3 pitchers for every game with pitchers pitching every third day/game.They could then have another 3-4 relievers who would be 1-2 inning guys to come in if one of the three gets into trouble.
So the #1 pitchers in the league would pitch in about a third of the games (54) for 3 innings max (162 innings).PItchers would have to train their arms different.Each team would also need 9 primary pitchers versus the current 5 starters.
If that first time thru the order is so much better, this seems like where they will end up.And won't all those 1-0 games be exciting?Only problem is what happens with double headers and extra innings?Every team will need a couple Chris Giminez type players.
I think the intent is to get the same (or even more) IP from the same guy. But he starts his third time through the order with the opponent's 4th or 5th hitter, instead of starting from the top of the order.
