You can call it anything that you want - common sense, tradition, new age thinking, etc., etc., etc. - There is not one best way to set a lineup. There are and will continue to be many ways to get the job done. For those who want to put their best hitter at the top of your lineup, what criteria are you using to define your best hitter. The ideal player to plug in to each of the spots in a lineup does not exist. I think that I will defer to the professionals on the field. My assumption will be that they have used many pieces of available information to determine their lineup and that it is not set in one particular way just because that is the way that it has always been set. If who you consider to be your best hitter possess a combination of skills - the ability to get on base as well as the ability to produce runs, and you choose to slot him at the top of your order, go for it. If I slot him in the 3 or 4 hole and get up on you early because I have some pretty good OBP guys in the 1 and 2 slots, I like my odds of winning better than yours. I still appreciate not over thinking things too greatly. My approach may be to simplistic but oh well - It has worked, it works, and it will work continue to work. Oh by the way, if my pitchers are better than yours, you can set your lineup any way that you like but I wouldn't lose too much sleep over it. I am going to beat you anyway most of the time.
