Ugh all of this just feels so wrong to me, boomer me or whatever as many people do over my 'stuck in the past' views on baseball but I don't want to watch a game with a designated hitter, I just find it utterly boring. Some of my favourite moments come from the rare times a pitcher makes a good hit and there is a lot of strategy to be had in putting your pitcher in the batting box, Koo Dae Sung running the bases on one of his only games and scoring against Johnson, Bartolo hitting a homer. There are some great moments that come from a hitting pitcher and it means that you have to work around a disadvantage in the order, the DH isn't for me.
As for the leagues I'd honestly go out on a limb and say there isn't a huge group of fans truly calling for them to merge so I won't even touch on that. Ridiculous idea.
