I didnt care much for turf fields myself, but when they were all the rage in the 70's they actually contributed to a game that played well to speedier players and fielders. Also, more injuries since the turf was basically fuzzy plastic stretched over concrete.
Some teams with their fan bases spread out over larger rural areas (Kansas City for one) installed turf because it drained better and they could avoid rainouts that made people wary of driving 100+ miles to see a game.
The original Comiskey Park actually had a turf infield and natural grass outfield for a while. You can sort of make it out in this pic
It isn't the turf that bothers me that much--sure, I'd reather have grass but I GET all the advantages to turf.
What bothers me is the FULL TURF infield. There is no dirt basepath, only dirt 10 fet around the bases. The other 80 feet is all turf. It looks dumb, plays dumb and I don't like how it looks on tv. Selfish, you bet but I was watching the game last night and it was just annoying me.
