It's three weeks into the season and I thought it would be interesting to compare the actual standings against the Pythagorean standings. Bill James first introduced the idea of calculating a team's projected performance based on their runs for and against, which he called the Pythogorean formula (Win = Games * RF^1.83 / (RF^1.83 + RA^1.83). Actually James used to the power of two, but I prefer 1.83. I'm kooky that way).
It's a small sample and the differences may be meaningless, but the Pythogorean formula may be a more accurate way of calculating actual performance and predicting first half performance. So here 'tis:
It makes me think that the Royals', Giants', and Mariners' leads may be shrinking, and that the Phils', and Yanks' may be expanding soon. The Cubs should have a better record, but so should the Cards. The two West divisions may be the most interesting (again) with three or four teams remaining competitive in each.
