The World Series begins on Tuesday night. The Los Angeles Dodgers have home field advantage and will host the Houston Astros in Game 1. The preseason odds of this exact World Series matchup were +4975. L.A. (best odds to win title were +1000 last October) hasn’t won it all since 1988 and the Astros (best odds to win title were +1200 last year) never have. Before the first pitch of the series, here is a betting preview including odds, trends and prop bets.

World Series Betting Trends since 2005

Moneyline Favorites: 40-25 (61.5%), +4.35 units

Home teams: 37-28 (56.9%), +1.63 units

  • Home favorites: 29-17 (63.0%), +3.64 units

Zig-Zag Theory

A well-known betting strategy is the Zig-Zag Theory, which simply takes a team if they lost their previous game. The reasoning behind this system is that teams will try harder to avoid elimination after a loss but it doesn’t work in the World Series.

  • Betting teams that lost the previous game: 22-29, -8.86 units

Fade Teams that Lost Previous Game as Favorite

We know the Zig-Zag theory doesn’t work, so it’s smart to fade a team after a loss. It is most profitable to target teams that were favored in the previous game: 14-6 (70.0%), +6.16 units.

Betting against the public (50% or less of ML bets)

Fading the public is the simplest strategy in sports betting. It works at every level of the MLB postseason.

  • All postseason games: 235-202 (53.8%), +67.05 units
  • World Series: 37-30 (55.2%), +10.47 units
