FanGraphs Power Rankings: August 15–28

With the playoff pictures in both leagues nearly settled with a month left to play, big matchups between the best teams lose a little meaning without the high stakes of a close pennant race hanging in the balance. Still, there are a few competitive divisions, and the Wild Card race in both leagues should be exciting down to the end of the season.
A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (a 50/50 blend of FIP- and RA9-, weighted by IP share) — and combine them to create an overall team quality metric. New for this year, I’ve opted to include defense as a component, though it’s weighted less heavily than offense and pitching. Some element of team defense is captured by RA9-, but now that FanGraphs has Statcast’s OAA/RAA available on our leaderboards, I’ve chosen to include that as the defensive component for each team. I also add in a factor for “luck,” adjusting a team’s win percentage based on expected win-loss record. The result is a power ranking, which is then presented in tiers below.
| Team | Record | “Luck” | wRC+ | SP- | RP- | RAA | Team Quality | Playoff Odds |
|---|---|---|---|---|---|---|---|---|
| Dodgers | 88-38 | -4 | 123 | 79 | 80 | 2 | 180 | 100.0% |
| Astros | 82-47 | 0 | 113 | 85 | 81 | 18 | 181 | 100.0% |
Despite nine wins over their last 13 games, the Dodgers have slowed down just a touch, though they’re still on pace for 113 wins this year, or a .698 winning percentage. History awaits if they can crest the .700 mark: Only the 1998 Yankees and 2001 Mariners have finished a full 162-game season with a winning percentage that high or better. After wrapping up their series with the Marlins on Monday, they have a tough stretch of games ahead of them: three in New York against the Mets and then six games against the Padres split up by a three-game set against the Giants. If they can get through this part of their schedule at their current pace, they’ll have a good shot of becoming the third team ever to finish with 114 wins or more.
Even though they just dropped two of three to the Orioles over the weekend, the Astros have elevated themselves over all the other teams in the American League. Houston has played extremely well all season long and has a soft schedule on the docket, with six straight series against teams with records below .500. Of some concern: the Astros scored just four runs total against Baltimore. Justin Verlander, the favorite to win the AL Cy Young award, was also forced to exit his start on Sunday with a calf injury. The offensive woes should sort themselves out, but losing Verlander for an extended period of time would be a serious blow. Read the rest of this entry »
