I view the pitch count with a jaundiced eye.
It can be very useful when you have a pitcher who has just come off rehab. His pitch count has to be monitored at the start, and I've seen how this is done in the majors---they'll start him off with 50 or 55, and if after a couple of starts he seems to be doing all right they'll gradually increase the count, 60, 70 and so on, until they get to the number of pitches he can handle without reinjuring himself. But when you have a situation where regardless of how well the pitcher is doing, he goes six innings and out he comes---this I don't like. No wonder the number of complete games has fallen off the way it has, because the way they baby and mollycoddle the pitchers and don't give them a chance to go really deep into games results in one thing and one thing only: overworked bullpens! And this starts in the minor leagues!
I remember way back when, there were three-man rotations, sometimes four, and those pitchers would really go deep into games, go the distance, and only one reliever was needed. And that reliever could go one or two innings---or seven; I'm thinking of the Yankees' Joe Page who could go 6 2/3 and shut down the opposition. Everything was just fine until the advent of the designated hitter, and then things changed---and in my opinion, not for the better. A large part of the problem is the fans who wanted more and more home runs, and so we very rarely see the good old-fashioned scoreless pitchers' battle.
It's enough to make one want to take up tiddlywinks.
