ZiPS Updated Playoff Probabilities – 2018 World Series

The ZiPS projection system will update these tables after every game and as the starting-pitcher probables change. They are based on the up-to-date ZiPS projections of the strengths of the teams and the projected starting pitchers. They are different than the playoff odds that appear elsewhere at this site. The FanGraphs playoff probabilities are based on 10,000 simulations using the updated projections in the depth charts. Where ZiPS differs is by guessing the game-by-game starting-pitcher matchups and using the ZiPS projections, including split projections.

First, here are the game-by-game probabilities:

Game-by-Game Probabilities, World Series
Game Home Team Boston Starter Red Sox Win Los Angeles Starter Dodgers Win
1 Red Sox Chris Sale 100.0% Clayton Kershaw 0.0%
2 Red Sox David Price 100.0% Hyun-Jin Ryu 0.0%
3 Dodgers Rick Porcello 0.0% Walker Buehler 100.0%
4 Dodgers Eduardo Rodriguez 100.0% Rich Hill 0.0%
5 Dodgers Short-Rest David Price 39.1% Clayton Kershaw 60.9%
6 Red Sox Chris Sale 60.6% Hyun-Jin Ryu? 39.4%
7 Red Sox Nathan Eovaldi? 54.8% Walker Buehler? 45.2%

And here are the overall series probabilities.

This is pretty interesting, ZIPS basically favors the Dodgers because of the Porcello vs Hill @ LA matchup, with everything else a coinflip.

And even though thin margins, the Red Sox are favored in 5 of the 7 games.
