FanGraphs Power Rankings: September 12–18

A bit of an abbreviated power rankings this week since I’m in the middle of moving. There isn’t much movement in the standings to report on anyway; the best teams continue to coast into the playoffs, and just a handful of teams are still fighting to keep their playoff hopes alive.
A reminder for how these rankings are calculated: first, we take the three most important components of a team — its offense (wRC+) and its 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 | 101-44 | -5 | 122 | 81 | 78 | 6 | 183 | 100.0% |
| Astros | 96-51 | 0 | 114 | 83 | 77 | 22 | 183 | 100.0% |
The Astros joined the Dodgers as the second team to clinch a postseason berth last week and could lock up the AL West as soon as today. They might not be on the Dodgers’ level right now, but a few of their key players are heating up at exactly the right time. Justin Verlander made his return to the mound on Friday and pitched five scoreless innings against the A’s with nine strikeouts. In that same game, Yordan Alvarez blasted three home runs; he’s collected 14 hits and six homers in his last seven games. They have plenty of strength throughout the roster, but those two players will likely carry the team deep into October if Houston is going to make a run at another World Series appearance.
