However, managers let pitchers go deeper if there is a perfect/no hitter on the line. If a pitcher had a no hitter and went deep into the next game with no hits the manager would most likely let them keep going. Also, typically (not always) pitch counts stay down with no hitters because there aren't a lot of baserunners. I don't think the lesser complete games these days would be a factor. The actual performance of maintaining a no hitter would be the deciding factor more often than not.I voted back to back to back no hitters, but it is probably a realistic tie between that and 2,663 games played. Neither one will be done in today's modern game. Pitchers don't complete games very often and the likelyhood of being allowed 3 complete games in a row with pitch count monitoring is pretty slim. Unless Dusty Baker is the manager. And no one is getting 2,663 games without a day off with load monitoring anymore.
