Oh, hello again.

The 2014 MLB playoffs are upon us, and that means it's time for Rational Pastime's (nearly) annual postseason projections. I won't be authoring full posts until both play-in games are complete, but I would like to share with you the output from RPBlog's new rating system.

The new system is very similar to last year's, with a few key changes. Estimated true records now take into account park factors and Patriot's David Smyth's Base Runs system for estimating run differentials. These modifications have improved the RPBlog system's accuracy by a full percentage point (which is actually quite a lot). I'll go into more detail in future posts, but for now you can see the raw data we'll be working with by clicking on "Power Scores" at the top of the page. As in past years, these numbers will update with the conclusion of each day's slate.

Here are the rankings and scores of our playoff teams:
  • Washington Nationals: .584 (1st in MLB)
  • Los Angeles Dodgers: .578 (2nd)
  • Los Angeles Angels: .572 (3rd)
  • Pittsburgh Pirates: .561 (4th)
  • Baltimore Orioles: .557 (5th)
  • Oakland Athletics: .551 (6th)
  • Detroit Tigers: .538 (7th)
  • San Francisco Giants: .532 (9th)
  • Kansas City Royals: .518 (12th)
  • St. Louis Cardinals: .515 (13th)
