Yesterday, I took a stab at gauging the significance of the results from the American League's first month of play using two tools to estimate final winning percentages. One is our PECOTA-based Playoff Odds Report, the other a historically based formula derived by Rany Jazayerli, which incorporates a team's record to date as well as its results from the previous three years. As I said, Rany's study suggests that not until the 48th game do a current season's results become more predictive of the final outcome than the historical projections. In other words, it's too early to draw hard conclusions, but we can certainly glean hints from what's transpired so far.
The whole NL has been thrown into flux by the news on Manny Ramirez. Still, it's worth looking at the numbers to decide which teams are real (St. Louis?) and which teams will falter.
