Welcome to our weekly ranking of all the MLB teams! In this ranking, we use aggregate team hitting, pitching, and fielding statistics--not team wins, losses, runs scored, or runs allowed--to evaluate the performance of teams to date. You can think of the estimated winning percentage (eW%) below as how we'd expect teams to fall out if we threw teams with these aggregate statistics into one big league and let them battle it out for thousands of games. The table is sortable if you click in the header. All data are park-adjusted when possible. A legend is below the table, followed by commentary. There is also a table comparing actual vs. expected run scored and run allowed totals, as well as actual vs. expected winning percentages.

Offense = wOBA (park-corrected), eRS (estimated runs scored; wRC from FanGraphs, then park adjusted)
Pitching = tRA and tRns are a home-brew version of Graham MacAree's statistic.
Fielding = Fld: average of bUZR (from FanGraphs) and THT's batted balls statistic (converted to runs)
eRA (estimated runs allowed) = Pitching - Fielding
eW%lg = estimated winning percentage within the specific league (AL or NL)
LgAdj = league adjustment (bonus to AL teams, penalty to NL teams, because the AL has superior level of play)
eW% = estimated winning percentage if all teams were in one league (after league adjustment)

This Week's Movers:
Lest anyone (yet again) accuse me of methodological bias--my Reds, for the first time this year, rank last in these power rankings. It's been absolute hell. Before tonight's win, they'd won once in the prior 15 games. They haven't won back to back games since June 1 & 2. The losses haven't all been blowouts, but when you're scoring 3.1 runs per game, it doesn't take much to beat you. Worst wOBA in the league at 0.302. tRA is 12th in the 16-team league. The fielding has still been good--and the Rolen trade will help improve it moving forward--but while fielding is important, you can't get by on that alone. It's yet another sucky season. I'm tired of it.
The Marlins and Giants are on nice litte tears, and it shows here as well. The Rockies still are ranked well above the Giants, but are separated by just a half-game in reality. Aside from that, not much movement--except, of course, that the Yankees were unseated by the Rays after just one day. As I'm writing this, the Rays are up 6-4 in the 8th on the Red Sox in what is obviously a critical game. And the Angels are starting to open up some breathing room on the Rangers... Can they recover?
