The Least Important Batting Order Ever?

by Ken Arneson

MLB.com’s new A’s beat writer Jane Lee tweeted her suggested A’s lineup today. I found it hard to argue for or against her suggested order. It seems like every player in the lineup is roughly a .280/.335/.410 player, so it didn’t seem to matter much to me what order you put them in.

To test my hypothesis, I ran the 2010 Marcel Projections through David Pinto’s Lineup Analysis Tool. I don’t think the tool produces particularly realistic or accurate results, even though I had a little hand in developing it. But if it’s useful for something, it’s getting an estimate on the theoretical size difference between the best and worst possible lineups.

When I’ve run this before on potential A’s lineups, the difference between the best and worst lineups has been about 45 runs per year. For the projected 2010 lineup, the difference is 29 runs. And since no one is going to bat Coco Crisp cleanup with Jack Cust and Kevin Kouzmanoff eighth and ninth, you can probably say that any reasonable batting order Bob Geren decides to run out there this year will be about as good as any other.

I’m too lazy/busy to run the numbers, but it makes you wonder, how many teams in baseball history have had a lineup where the batting order mattered less than the 2010 A’s?
