I don't necessarily mind the shift, but what I do mind is what basically amounts to the 2B/SS playing in shallow RF. Yeah, sure, you can shift but you have to keep your feet on the dirt.
Similar with the pitch clock; I don't necessarily mind it but I would prefer for at least the first season or two to be a little longer (22-25 sec w/runners on, 18-20 w/bases empty). I like the idea of faster pace of play, but am not really a fan of automatic balls either.
