2025 AL, NL Pennant Odds: Who is Favored to Advance to the Fall Classic?

Two MLB teams from each league are set to face off for one championship pennant.

Let's check out the odds to win the AL pennant and NL pennant at DraftKings Sportsbook as of Oct. 12, as well as what to know about each series. 

National League winner

Dodgers: -200 (bet $10 to win $15 total)
Brewers: +160 (bet $10 to win $26 total)

What to know: The Dodgers and Brewers faced off six times during the regular season, and Milwaukee won all six games, outscoring L.A. 31-16 in the process. Three of the wins took place in Milwaukee, and three happened in Los Angeles. In addition, in four of the losses, L.A. scored a combined four runs. In short, the Brewers — in addition to having the best record in baseball — dominated the defending champs during the regular season. 

Still, it appears that Los Angeles' championship pedigree outweighs what happened over those six games. The Dodgers have made it to at least the NLCS seven times in the last 10 years (2016, 2017, 2018, 2020, 2021, 2024, 2025), they won the NLCS four times in that span (2017, 2018, 2020, 2024), and they won the World Series in 2020 and 2024. Milwaukee last made the NLCS in 2018 (losing to the Dodgers in seven games) and last made the World Series in 1982, losing in seven games to the St. Louis Cardinals. The Brew Crew have never won a championship. 

This postseason, the Dodgers are 5-1, with series wins over Cincinnati and Philadelphia. The Brewers are 3-2, with a series win over the Cubs. 

Game 1 is set for Monday in Milwaukee.

American League winner

Blue Jays: -130 (bet $10 to win $17.69 total)
Mariners: +110 (bet $10 to win $21 total)

What to know: The Blue Jays won four of their six matchups with the Mariners this season, outscoring Seattle 31-24 over the course of those games. However, the Mariners took two of the three in Toronto, and the Jays took all three in the Pacific Northwest.

Toronto finished the regular-season tied for the best record in the AL, and dispatched of the team it was tied with, the New York Yankees, in the ALDS in four games. Meanwhile, Seattle is 3-2 with a series win over the Tigers. 

The Mariners last made the ALCS in 2001 (they also made it in 2000) and have never made it to the World Series, while the Blue Jays made the ALCS in 2015 and 2016, and won back-to-back World Series titles in 1992 and 1993. 

Game 1 of the Seattle-Toronto series is set for Sunday in Toronto.
