The game is no longer about keeping a manager happy. It is about metrics which probably say that resting a player after a good run of games is better in the long run. By the way, I believe this to be idiotic and have since organizations began in the 1980s to use six sigma techniques, designed for manufacturing, as a way to "teach" leadership (developing leaders has been my business for quite a while). Metrics and management are for things, leadership is for people. Baseball players are people so they should be led by their manager, not managed as if they were things.
