I actually like 7 inning doubleheaders. It's been that way in the minors for decades. I think a case could be made that it would be more popular for the fans than 9 inning doubleheaders. It's not like the old days where you had doubleheaders on Sundays. With game times as long as they are, I don't know why anyone would want to go to one. They may say they do but if push came to shove, they would choose not to go or leave early. With 7 inning doubleheaders you're basically cutting off two hours. You may be able to play two 7 inning games in the time it takes for the Yankees and Red Sox to play 1 game. But you could also schedule them too instead of having them be the result of rainouts. You wouldn't have to schedule those money grubbing split doubleheaders anymore. With all the distractions at one's disposal, more people may pay attention to the games if they are two seven inning games instead of two 9 inning games.
