FanGraphs Power Rankings: August 29 – September 4
With only a month left in the season, the tiers in these power rankings have mostly solidified. There are plenty of interesting storylines to follow as the season winds down, though, with plenty of playoff positions still up in the air.
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.
Note: All stats are through Sunday, September 4.
Team | Record | “Luck” | wRC+ | SP- | RP- | RAA | Team Quality | Playoff Odds |
---|---|---|---|---|---|---|---|---|
Dodgers | 92-41 | -4 | 122 | 80 | 80 | 4 | 180 | 100.0% |
Astros | 86-48 | 0 | 112 | 84 | 80 | 19 | 181 | 100.0% |
Last week, the Dodgers lost their first series since dropping two of three to the Nationals in late July. They also lost multiple games in a row — a losing streak of three! — for the first time since that series against Washington. And with their loss to the Giants on Monday night, the Dodgers have now lost four times in a six-game span. It’s not all bad news in Los Angeles; Clayton Kershaw returned from the IL last week, though Tony Gonsolin replaced him on the sidelines with a forearm strain. Still, they’re on pace to break their franchise win record and are within spitting distance of topping the major league record set by the Mariners in 2001.
The Astros don’t need much else to go right for them this year — they’re already comfortably the top seed in the American League and the favorite to make another World Series appearance out of the Junior Circuit — but they got a nice boost anyway from their top pitching prospect, Hunter Brown, who made his major league debut on Monday night and held the Rangers scoreless over six innings. With Justin Verlander still sidelined with a minor calf injury, Brown should get an opportunity to show what he’s made of as the Astros ease into the playoffs. Read the rest of this entry »
